Registration issue fixed

Chris discovered that registrations had been disabled since June 8 because the "max_users" limit had been reached. The limit was set to be very high, but someone registered a large number of accounts, probably using some automated script. Nobody had submitted a support ticket, so we didn't know about it.

No action is necessary other than increasing the number of allowed users, as all that happened is that there are a lot of inactive accounts in the system.
