That saying if you guys REALLY want a wiki I wouldn't mind giving it a shot. Though I have exactly zero experience setting one up, though I have some experience writing for one for a school project. Looking at the manual the initial configuration isn't that hard (seeing as half the work is already done) and most time goes in setting up templates and such. I have nothing to do till 8 November (when my internship starts) and don't have a steady job at the moment so I'm, to put it mildly, a bit bored.
Although i appreciate the offer, we are looking for someone to take charge on long term of the wiki.
