Interface

I just upgraded to Diamond Membership, due largely to how pleased I am with the iPhone App. Unfortunately, I'm finding that the web interface for the Chess Mentor has some annoyances. In particularly - the "Next" and "Back" buttons keeps getting moved around such that clicking "Next" Twice will actually move you forward once and then back. This is a terrible interface design, and gets old quickly. How can I report a formal bug on this so that it can be remedied?

Here you go.  There's a Mobile department listed on the drop down menu.

Thanks, I've submitted a bug report. This is actually for the web version via the browser, not the iphone, though :)

I have been thinking about purchasing the standalone chess mentor. Is there any difference between the licensed app on chess.com and the standalone version ?

Outside of a crappy interface and maybe 40 or 50% of the content, no.
