I have been following as an unregistered member and decided to join the action. I don't think a sportsbook acct is required but am interested in the answer from a mod.
There are plenty of contests in the Handicappers Forum: http://www.sportsbookreview.com/forum/handicapping-contests/
I run a weekly NBA and NCAA contest that only cost 20 betpoints. Other contests vary in entry fee, so check it out and find the one that best suits you.
Personally I would never blindly follow another handicapper, but the Service Plays area does offer some great cappers to either follow or fade.
