Personnaly I can help with :

-DirectX : can be the DirectX Headers or DelphiX, especially Direct3D and Direct Draw.
-Algorithms : if it's needed, I can explain the basis of the most current algorithms and give some examples in the domain of games.

This year I'm still a student, so I'll have some time to handle my projects. BUT (yes there's a but ^^) DGDev would not be my only project (actually I've got an other website and a video game). But I'll have some time to write for DGdev don't worry about that(but not 5 tuts a week ^^)

And, just remembered something ... We'll need somebody to correct all the mistakes I could make in a tut (since I'm not English, I can and I will make Mistakes).
