If you add iPhone support I will buy a gold membership!
this feature would appeal to approximately 6% of our users :)

good point!!
I think that having chess.com support would be much easier now with the 2.0 update on the iphones. The programming staff would just need to make a program (written in Cocoa Touch I believe) that would link to chess.com's list of turn based games.
I think many of us would be happy to pay upwards to 10-15$ for such a program on the iphone, on top of the standard membership fee. Even us poor students who are miserably addicted to chess :(

And I'm not talking full support, just enough tweaks to the game board javascript that I can play!
Imagine that sweet sweet $29.95 in your bank account :D
