May I suggest Carol that if you have the capability to restrict any new members after registration from posting until you can send them an email for a rsponse. This way you'll have their IP address with a name. If they post spam you can then block their IP address and since most people have Broadband now the IP address most always stays the same per PC. Dial-up is different. You can also tell by funny sign-in names if they're legit before allowing them access to the forum.
