For a bit, I've popped the idea of a Wiki around on the Mac Rumors chat. Tonight, I sat down and installed MediaWiki on my hosting provider's server. Here is the PowerPC wiki in its current, albeit sad, state: http://apple.128keaton.com/wiki/Main_Page. To make a new page, simply put in the address bar http://apple.128keaton.com/wiki/*page title*. We have a G5 page in the works (http://apple.128keaton.com/wiki/PowerMac_G5), but it could use some love. I hope this turns into something big.
