A while back I helped a few people join the RPF who were having trouble signing up, I just noticed that registration is open again this year so I thought I'd post this for those who are interested.
I've met a lot of great people here on the Dented Helmet and also the Replica Prop Forum, here is the information copied from the RPF post, I hope this helps...
Scheduled Open Registration - November 1st - November 15th
To register on the RPF, you must submit a legitimate e-mail address fromyour ISP (ex: Earthlink, RoadRunner, Comcast, etc.) for verification purposes.
Registrations from FREE email accounts (ex: YAHOO, HOTMAIL, GMAIL, etc.) are NOT ACCEPTABLE, and will be denied activation and subsequently removed. To register on the RPF you must register with a legitimate e-mail address from your ISP (ex: Earthlink, RoadRunner, Comcast, etc.) for verification purposes within the registration period and must maintain a legitimate email address on your account at all times. There will be NO EXCEPTIONS.
