If you are a new user and read your email on yahoo.com:

We just discovered that registration confirmation emails from bmwmoa.org are being caught by Yahoo's Spamguard filter. The email goes into your bulk mail folder if you have Spamguard turned on and you'll never see it in your inbox.

To complete the BMW MOA forum registration process, you will need to look in your bulk mail folder for the confirmation email, then click on the link.

Otherwise, you will be relegated to the purgatory of usergroups: "Users Awaiting Email Confirmation," and will not be able to post on the BMW MOA forums.
