I wouldn't bet against you on the five bucks, of course. I couldn't find how to change my username in the control panel. Under which heading would that be?

Thanks for your clarification about the accounts. If I now establish a new user name in the other profiles (all lower case, same name), without either changing my username to all lower-case or re-registering in the talk section, can I still link the secitions, or do the usernames have to be identical in terms of lower/upper case?

Excellent that the powers that be are informed, as I assume even less tech savvy N900 users than myself are going to be joining this community.
