Much ado about wiki

Wikis are so much easier than I thought they were! I have just started one for a 20 year school reunion.
Email had made it easier than it would have been just with telephones and letter writing, but even with email once the mailing list got bigger it was harder and harder to keep track.
As soon as I started the wiki I could see that it was going to be much easier as long as everyone else uses it.
I simply can't believe how easy they are to use. The possibilities for them are huge! Even things like roster availibilities for staff members or library holiday activity bookings could be done this way.
I am planning to investigate what sort of things wikis are being used for.
