Wiki... bad?

So using a wiki has greatly helped the design process, it's (in my opinion) the best format for doing this stuff in. Unfortunately it is... Down-ish?

Every few hours the site becomes inaccessible, Chrome/Firefox says the page will not load/isn't responding/etc. A little while later it starts working again. This worried me because of a vandalous message on one of the main pages of wiki-site itself that warned that spam was attacking wiki-sites and that the administration was doing nothing about it (and oddly the message was staying there and had been there for quite a long while). The message was written by someone with admin access, and was very colorful (literally, green and red colors if I remember right).

This makes me want to use a different service for my wiki. Now, I will only use a wiki that uses mediawiki and that allows monobook as the skin/theme/CSS (so Wikia, the largest competitor, is out). or a monobook-like skin would work actually, but I wouldn't use anything that uses pictures in the layout or that's too colourful (it's actually a bit more complicated then that as to which skins I'll use, but pretty much it's limited to monobook so it's not important).

Unfortunately for me there is no such service so far as I can see. Google Sites wiki? Wait what?

It's now been over an hour since I was last able to access the wiki, I need to have the game mode determined soon so that I can move on to the rest of the game design, and wiki-site isn't working for this at all. With Google at least the site would be accessible... But no, of course it doesn't allow either monobook or wikicode (it's all done in some wyswig-style editor garbage GAH).

Currently the only option I have is to use a openoffice document on my computer... but putting the entire design into one file would be a horribly ugly way to do this (which is why I'd rather not do that). I originally went to wiki-site a few days ago for another project I was working on (planning my GURPS campaigns), and I realized it would be a good place to plan Muddy. Unfortunately it appears that my only options at this point are:

1) use OpenOffice
2) install mediawiki on my desktop and use it there.

the problem with 2 is I'd have to install PHP and Apache before installing mediawiki and I've done that before and it wasn't fun. In point of fact it was not terribly unenjoyeable, it just took a lot of time and the fact that it eventually got working was in no way because I understood what I was doing or that something I did worked, but rather that the GM was feeling sorry for me so he just made the installation work automagically without properly explaining himself. I don't want to rely on the GM's charity.

So Openoffice it is then!

"yay"
