Hey Greg,
I like the idea of a member having to make a number of log-ons before being allowed to email. A number of other sites require five to ten log-ons before mailing. Also, I would really limit the number of email for nonsubscribing members to only a couple per day. I am concerned that to disallow email without a buddy confirmation might hurt. I really appreciated being able to email divers and ask about their experience at a certain site that they list - without trying to get a buddy approval first. Thanks for all you guys do!
