I have needed a simple wiki solution for a little problem of mine, and I have found just what I was after.
I just needed a page or two that could be easily edited for the handful of people who are attending the Palimpsest Big Day Out in May – usually this stuff is handled on the forums, but this can be a nightmare when you are hunting through pages of messages. Installing a whole wiki on my webspace would be overkill, so I needed a hosted solution.
Steve Rubel yesterday pointed to StikiPad which I have a go, and it was ok, but the free version only allows for 5 revisions! Rubbish.
In the end I found PBwiki through Google. And it is perfect. Simple to set up, a simple method of user authentication, revision histories and everything else you might need. OK, so the free version has adverts and certain limitations about the number of pages you can have, but it is perfect for almost any simple wiki needs.
