Is it possible to moderate new topics only? I do not want to moderate replies to the topics. I have mail connector on for few forums, and auto subscription set to send new topics only. Many members post spam/advertise by starting a new thread. Other members complain a lot.  

where is the Like button when you want it  

This also falls in a topic we have had for years, I still have not figured out how but you should be able to set a require number of post for new members before they get unmoderated. This would prevent spammers from getting their post to the public.
