I'm running into the same exact dilemma, ctown79. What I believe is goin' on is that Wickedfire has a filter that catches posts in the SBT sub-forum if they're coming from people who are relatively new to Wickedfire in general.
What I suggest — and what I'm currently doing — is that you either create intelligent threads in the Newbie Forum asking thought-provoking questions that generate intellectual discourse, or you hop around the other sub-forums and chime in with your two-cents on topics you can actually contribute quality advice in.
The whole reason the filter's there is because it looks kinda sketch if your first few posts are directly targeted at the SBT sub-forum. I assume plenty of people have been burned by 1-post wonders in SBT, so as a precaution, Wickedfire has their framework to flag posts for approval that come from people who haven't established themselves.
Give and you'll get. Good luck, son!
