These are all my personal opinions, so they may or may not seem reasonable to you.
Well to be honest I don't like the home page design or layout very much.
First of all it's a bit on the wide side for those of us with smaller monitors (Or maybe everyone, I don't know.) You have a sort of (imho) amateurish approach of just leaving the right side open. Instead, I would strongly advice closing the boxes on the right at least places with text in them. It makes it look a lot less cut off and distracting.
Also, in my opinion, your fully rounded logo looks off when placed next to the very boxy and right angle-y design of the rest of the page.
I would (this is really kind of nitpicking) darken the areas where there is text just a bit, it makes it a lot easier on the eyes to read.
Also-- to users logged off at least-- there is no edit [(which may be your choice)(and in that case I recommend at least allowing "view source")] or discussion tabs, which seems important to me.
This may seem pointless, but I always thought random page is a really nice addition to a wiki site and missed it on yours.
I think some sort of featured article or the like would be a nice addition. (Besides incentive to put in good work, showing off good work, etc, it also gives the newb brand new to your site ((like me)) a chance to 'physically' look around your site. The box down below is a nice start, but besides that it leaves people who don't know SMOD with no idea of where to start.)
Also the captions boxes are fugly, and the (don't know what it is called, since I can't edit or view source) setup for where you cvars for things on an individual page is imo _really_ annoying. It's not like you have to worry about running out of room going down, so why the hell are you hiding words from me?
I also don't really like the way pages are titled in the url. Maybe it will be good, but I don't see how having (for example Soy Beans) "weapon:" in the url will help identify it any better, unless you're worried about different soybeans? I would just change it to /soy_beans, and than maybe put weapons in the title, or even better, just template it. (Maybe I missed it but I'm not seeing a whole bunch of templates, and those, ((connected to a readable, acccessible table page)), make it much better organized.)
That's all I can think of, and despite all the critisim, I think it's not bad overall, but I figure the critisisms will be more helpful to you than just gj!
Edit: Wooah that's a lot of words. Well I hope you find some of that useful.
