Ugh. This is the one I do not, do not want to do. I do not like them, Sam I am! And being a mentor, I saw all the emails about the problems that different people had with the wetpaint wiki. What I don't like about most wikis is that you need an account on the wiki server to change any content. Sure I have a wikipedia account, but why do I need one for every random wiki I come across. I know that NTRLS uses them with some of their committees, but I'm still not feeling this one--unless the software is more like wikipedia and less like a clunky web page editor.
See, I've even edited some wikipedia pages...

More than that, but you get the idea.
Well after doing the paint, it is a lot easier than the pbwiki and has a nicer editing surface as well. Recommended much more than pbwiki
