Imagine, for example, that you're talking to a friend or colleague on the phone, and you decide that the answer to the problem you've been discussing is for the two to you to sit down and draft a letter or document. The wonders of modern technology means, of course, that there's no need to wait until you can get together in the same room, in front of the same computer screen.
All you need is for each of you to head to the nearest computer and log into www.qikpad.co.uk. Think of a title for your document, type it in, and both surf to the same web address. Within seconds, you're both working on the same document in real time. As you type, your words and edits are instantly reflected on the other person's screen. Separate colours are automatically added to make it clear who typed what. And if there's more than 2 of you, additional people can even join in too.
Qikpad is one of many such collaborative editing services, but it's also the simplest I've seen. It's free, quick, and there's no need to sign up or log in. Which makes it slightly unsuitable for discussing your next corporate takeover, but for low-risk documents it's very clever indeed.
So next time you're planning a letter, document, table plan, party arrangements, or anything else that needs input from multiple people, give www.qikpad.co.uk a try.
