Good work. It is hard though, you have to really think about what colours you want everything. I have done a christmas one for movie site just to fiddle again. You have to make sure all the text is clear too, I can't read the navigation menu, but I did the same to start with, its knowing what each option means. Still, you can see how much fun it could become can't you!
Have you got to grips with the skins in aimoo? There is something that I'm not so keen about on aimoo. I recon though that yuku will be looking at ways to make it possible to migrate msn groups and to have html borders same as msn.
