It's funny, what with everybody talking about C++, but what I want is more Lua scripting. I think that the best thing to do (for Lua and C++) would be to have more documentation on the wiki. I plan to help on that as soon as I start to be comfortable with the scripting. But it's silly that there are red links on the pages for basic functions. Hopefully the docs can get even better, as that seems to me to be the biggest problem.
EDIT:
It seems that I cannot edit the wiki. Do I need to request an account or something?
