Zi Makki has just setup his Wiki for a geek dinner after the MSDN Roadshow on the 21st March in London.
The ones I have been too have been loads of fun, so if your going to the day and can attend I do recommend it. Hopefully I’m going to the day, not sure if I will be attending the dinner due to the amount of work I currently have on.
Also check out http://www.screwturn.eu/ what he is using as his Wiki. Its built using ASP.net 2.0 (I’m guessing from the file extension). I’ll install it tonight and post a review sometime this week as I’ve been wanted a ASP.net wiki for some time.
