Just FYI for anyone needing this. I had a few users signup for my site and they needed to create a Groupee account. They used a spam blocker on their email which requires manual intervention for allowing email through to them. The address Groupee uses to send the verification email is groupee@infopop.com, have your users add that to their allowed mail lists and they will be able to verify their new account.
This is actually one of the things I came to infopop nation to post about today. We just opened our website yesterday, and after having a major problem with groupee being down, a lot of our members are having their verification emails to their Spam folders. We think that this is a nessecary update for groupee users. Jenny
