Nice job so far, looks like we got a few excellent editors already.
Looks like Arson remade a downloading & installing page (had similar stuff in
http://wiki.c-rpg.net/index.php?title=Getting_started), making the steps a lot less detailed. This is of course a matter of opinion, but I think the newbie guides and basic install steps should rather be too detailed instead of too vague. Someone often pops to IRC or makes a forum post requesting help about stuff that seems trivial to anyone who's played the mod for any time at all. I'll re-add the details later if no one strongly disagrees.
Another important thing: let's try to make each article have a short overview, just like normal Wikipedia. A short paragraph or two giving the basic impression of what the article discusses in detail. This way people can get an overview without reading through the full article - you don't want to read through every detail when you've just started to play. Newbie-friendliness again.
