1. Servers will be able to do alot more with our mod then they have with SSAOW, From gametypes to vehicle/mine limit to limiting characters per team...anything that we can control can most likely be set by an admin.
2. UT3 is coded in C++ (90% sure), another part is kismet scripting, but you wont need to learn that at all, a server.cfg file should have everything you want to change in it...also at server runtime, we should included a vote/admin GUI similar to "mani's mod" for CSS
3.Well, as far as textures, we dont plan on adding anything special in that area that doesnt allready ship with UT3, if UT3 has a server side decal placement, then we could use their option for our mod.
4. I dont understand, symbol/objects?..what are you referring to?
We may need your help, at this time I'll go thru our current coders and see what needs to be done, I'll need some example of your work, you can PM me with links to your work if you'd like.
