Alright, I am trying to set it up so my platinum usergroup can post unlimited ads for free. My registered usergroup has to pay a small fee to post each ad. And both groups have to pay a little extra for highlighting/bold/etc.
However, both usergroups right now are able to post ads freely. How do I fix it so that it charges the registered users to post an ad? Also, where do I set how much it cost? Also, how do I set it up so they can add highlighting/bolding/etc for a little extra?
