Everyone who had a Sep7agon email and still wants access, post in here. I have all your old email and will re-create your account, add the email to your account, and send you a temporary password.
Once you get your login, go to http://sep7agon.net/webmail and allow the security exception (we don't have an SSL yet); don't worry, it's secure. Go there and click on your account name in the upper right and choose the password / security option to change your password.
From there, go to http://sep7agon.net/email/ to use the ultra cool webmail thing.
EDIT 2: We're using Zoho to host our email. Everyone will get 5GB of mail storage and a pretty cool webmail interface and an app if they need it (for email, not the site).
