I surprised this hasn't been moved to the recruitment lounge yet, but that's where this should be.
Incidentaly, its not hard to do if you want to do it yourself.
You merely colour in the textures that are already used, then in O2, you Ctrl-Click on a texture in the texture window and press 'E' to bring up the face properties. Then you can change the texture to the one you altered. Or, save them in the original folders as their original names and then you don't even have to fiddle around in O2
