I believe that usually the e-mail is confirmed succesfully and the internal error shows up because it is tried to be confirmed again. Can you host games?
Confirmed. I can host games now. Please:
1. Replace the "Confirm" button on my account page with a "verified" or "confirmed" icon so that I can see if my account is confirmed.
2. Better handle when I've double-confirmed my account. An error message other than "Internal error" would be nice. Maybe something like "You've confirmed your account." (i.e. make it look like everything is OK).
