Here is a site my brother and I are working, and we plan to release it this week.
It's a tutorial database site, dealing with game development. I think it could be useful to programmers, artists, every aspect of development.
I think I may add news to it, or some other items to keep users coming back, but this is how i am gonna release it.

I posted a very early version of it on this forum before, but now I think it's done.
Anyway, any comments, or suggestions, on the site? Before releasing it I just wanted to get some basic ideas or thoughts on it

I really like the site and the navigation !

One small suggestion: When i click on another subtree i'd like to have the tree that was opened before closed again.

For example i accidently click on "Programming" and then on "Visual Arts". Then i'd like to have the Programming-tree automatically closed.

I just prefer it that way, otherwise nothing to add
