UBB.threads PHP Forum Software Community Forums Resources and Customizing How Do I? Default Group(s) for New Members

I created a new "Novice" group and put new registered members there.
They cannot use PM or Shout or email other members

when they posted 5 times they are moved to USER group.

It will give me a better chance to discover spammers cause they tend not to post relevant posts within thread or site topics.

Thanks for your advise
