Appreciated your valuable suggestion. Diigo is now added in the list.

while I'm at it...
My suggestion for an Email service that let's you schedule your mail:
Deferred Sender
While LetterMeLater has the added feature to send recurring mails and set up groups, I find Deferred Sender easier to setup and more intuitive to use straight from any email application.

My suggestion for Best Free Disposable Email Address:
Big advantage over GishPuppy is that you can create a limitless number of disposable email addresses even when you're offline. You just add any word combination before your Spamgourmet username and that's it. E.g. you can email me at I can set how many times this address can be used (5 in this case), I can change this or make it permanent for trusted senders anytime. There's a "no-brainer" and an "advanced" mode, so this should work for everyone.

Another tip if you want to post your email address securely: That's so simple and effective, just try it out. Here's my email address: (I trust no spam robot will crack this.)

And finally there's PrivNote Interesting service if you want to send one person a confidential note. The link to the note can only be used once, after that the note is deleted. Remember, ALL of your emails can be viewed/archived by certain authorities (don't want to sound paranoid, but that's just a fact).

Thanks Sammysoul for the info. I'll look into your suggestions.

[Update: Privnote, Spamgourmet and Scrim are now added and grouped under "Security and Privacy" in the list. Thanks again.]

Great work Jojoyee! Even though I think the way you presented Spamgourmet, it sounds kinda bad.:( Only 3 forwards... In fact you can decide between 3-20, change it anytime, or even make it permanent for trusted senders.

by Jojo Yee on 12. August 2010 - 4:08  (55834)

Thanks for your kind comments. I've now rephrased it and hope that's better.

my suggestion for Best Free Meeting Scheduler:
When Is Good:
I have never seen a more intuitive web application. Super-easy marking of your availability days as well as very straightforward for your contacts, even the technically challenged. No sign-up required. You'll get a nice short link for the meeting to send out, that's it.

Thanks for your feedback and it's now updated in the list.

Another website I use for online games is it gets updated every Thursday with a really good selection of games.

I am a big fan of note taking software, and especially like those that use the web. That way my notes are available to me wherever I may, whether it's work, or on the road traveling, or at home. I also like my notes application to be dead simple to use.

I've started using something called Notey, which is simply a blank web page that you can fill up with little post-it style notes. You can over lap them or line them up on a grid, or just slap them wherever. It can't keep track of media, and you can only type an url into a note but it won't turn automatically into a link. It's simply a text note tracking application. But for some things, all I need is a text file.

I use it primarily as an idea board, to capture ideas whenever a thought occurs to me. My work computer is locked so I can't install applications or software on it, yet I have to find some way to record ideas or inspiration so that it's available when I get home. A notebook would work as well, but only adds to the junk I'm already carrying in my bag.

It won't work for tracking the notes for your dissertation, but I think it fills a niche.

Sometimes getting a full white page when logging in again after logging out. Any ideas?

"Gmail ... filtering out exe and zip files."

Gmail filters out exe files but not zip files (unless they contain exe files). But this can be circumvented by encrypting the zip file.

You're spot on JF and appreciated your feedback.

I've found that the best free fast translator is Reverso.

Very impressive list. Thanks Jojoyee!

An excellent free online learning service. You have to sign up for it but if there's a catch i've yet to find it:)

Under "Best Free PDF Tools", I found out about:
If you need to merge/ split a PDF once in a while, they can be useful. No registration is required.
The copyright notice at the bottom each site is old, but they work.

Merge limits: 10 files & 5MB/ file.
Split limits: 20MB/ file.

Just wanted to give a shout out to Toodledo for being the best online To-Do list. I find it superior then RememberTheMilk

by saschamaj on 11. August 2010 - 3:23  (55768)

I started out with RTM but have since moved to Toodledo for 4 reasons:
1. the ability to sort my tasks by "importance". A Toodledo algorithm that assigns a value to each task comprised by due date, priority and age.
2. The "hotlist", which is a customizable short list with the current tasks at hand. You can also "star" a task, just like in Gmail, to further mark important tasks.
3. The iphone app is only $3 and has full functionality without having to pay a monthly subscription (unlike RTM).
4. Browser bookmarklet that open your tasks in the sidebar, with full access to all functions.

As a web host, byet sucks. I wanted to try everything on this page but thought I'd get the hosting to put it online as I went. Can't.
Google docs won't let me paste and after jumping through all the hoops byet won't either. Useless to me.

Moderator's Comment : Deleted personal information including passwords, regarding byet account. Please do not post such sensitive, and personal information on such public places. We do not allow this.

by tonyh (not verified) on 17. September 2010 - 11:22  (57986)

No reasons are given for Byet being recommended. I did a bit of browsing and found that it was quite highly recommended on one review site, but so were others. I also found other free hosts that have more features ( byet don't offer cgi or ssi) and there are a number af extremely bad reviews quoting personal experience.
In the end, I concluded it's free, so you can't really trust it, and I may just try it myself. It's not critical.

Unfortunately one bad apple in the barrel calls into question everything else on the site, including free security software, which IS critical, and the credibility of the site itself.

Best Free Sudoku online

For me, one of the best free sudoku, kakuro and others, is from Dr Gareth Moore. It contains many different games, daily subscription, set of puzzles ...
You can record games, view the intermediate times, your time to complete each game, add comments, add an assessment of difficulty ...
Very comprehensive!

This is my first comment, but I visit this site for over a year and am very happy with the work. Gizmo and collaborators keep it up;)

by Jojo Yee on 1. June 2010 - 3:38  (50757)

Thanks for mentioning Puzzlemix which looks good to me. I'll try it a few more rounds to see its strengths.

by Anupam on 31. May 2010 - 21:21  (50741)

Thanks for the suggestion, and for the comment :). Please do keep posting :)

by Saki on 31. May 2010 - 12:01  (50697)

Great list. :) Good work in compiling it. I would suggest Cometdocs and Zamzar in PDF tools. I use them every day and they are pretty much good and widespread.
