I just registered today.
Just a suggestion - in the "Membership Information" email, you send the username with the password. It would be a good idea to disable that feature, which I imagine is the default configuration, as it transmits security data in clear text unnecessarily across the wire. A general "Welcome" email would be useful so that users could determine which email address they used to sign-up and, possibly, their username, but the password is certainly superfluous.
If people lose their passwords, just let them use the password recovery facility.
