Sorry guys, I have to ask this question. I will close it when I found the "Holy Grail" for my project.
Long story short: I want to "wikisize" my worldbuilding project, and I tried dokuwiki and mediawiki. Mediawiki was a pain in the ass (sorry) and I struggled with it and I didn't liked it. Dokuwiki was the exact opposite: easy to start with it and it has nice UI. But when it reaches to a decent project size it drastically slows down (becouse it stores the pages in .txt files and not in DB)
Which wiki or software do you advice?
I'm a webdeveloper with some sys-admin skills so setting up a new program wouldn't be difficult.
