Looks nice. Is this hosted on your own server? Of course Wiki is needed. Can it host multiplayer IVAN when somebody writes one?
About mods, Atomic was the boss on jconserv.
AFAIK this is the fourth forum in IVAN history, not counting the Sourceforge forums. On the first IVAN forum we had a dark theme as default, and at jconserv we had it as an option. We also had a logo at jconserv (not sure about the original two), and at the first forum we had customized IVAN-themed icons, I think Atomic has them but had problems with convincing jconserv admins to use them, but I am not sure.
The name "IVAN Mods"... I think Arcane is right, if you modify the executable, it is usually called a 'variant' or a 'patch'.
Download links? You mean you can host our variants/mods here? The site were my 3d patch is currently on sucks (it did not when I created the first version), so I would use that.
