MediaWiki is probably the most standard Wiki software (ie. Wikipedia and friends) and it's written in PHP. It also supports ReST as noted in this thread. I've never heard of DocuWiki though, it looks interesting too. I haven't looked at PMWiki yet.
There's a few geany users around who could help with MediaWiki too, including any custom extension and skinning requirements (waving!)
[...] Personally I don't feel too strongly about which software, but I would think something familiar to people who may edit other Wikis would be good.
I reckon there would be more people conversant in basic MediaWiki markup than most other wikis' markup styles.
PS: I really like the idea of having a wiki for geany. Would probably contribute something, as I reckon would others who generally just lurk here.
