I see you're having a little trouble registering to access FreeGroups.net's MimerDesk Email Group system. I can help you with that, and I can send you your password if you forgot it!
The simplest way to register and get an account is to send an Email message with any subject to:
If you forget your password, just do it over again!
If you'll do that right now and wait 15-30 minutes, you should receive a registration confirmation message. Just reply to that message and your account information will be sent right back to you.
I hope you enjoy FreeGroups.net!
