Hello

I've read already some topics psoted on the forum but I think it's easier to post what I search for in a wiki..

I'm a multimedia student creating a concept for one of the school programs. sort of a class-wiki
Most wiki's seem to have a standard layout/design.
Is there a wiki that is totally customable? Where I can change the whole look and feel of the wiki? It would also be handy to have seperate user accounts so we can see who last changed the pages.. and I'd rather not have it hosted.. or if you can persuade me?

Can anyone make some suggestions? I'd really appreciate it!

(oh and my inspiration came from this wiki : http://art.yale.edu/ can someone tell me how it is build? or give me some helpful information?)

thanks!!
