BGH has gone a step further to keep the community spam free.

There are now three classes of forum users:
Guests - all posts moderated
Registered Users - 3 posts moderated
Activated Users - no moderation

For newly registered users, only the first 3 posts will be moderated before they appear in the forums. Other forum functions that are commonly used by spammers will also be limited in this user class.

After three approvals, users will automatically be promoted into the Activated Users group and new posts will appear immediately.
