Adam, it seems like you should have been bumped up to the next membership level by now. I don't recall the exact requirements to have the new-user restrictions removed, but it's basically "Show some interest in the Forum's subject matter and participate a little bit.". I believe you have to log in on a couple of different days, read a handful of threads (or at least parts of them), and submit a post or two. (Perhaps give a "Like" to somebody's post, but I'm not sure about that.)
Glancing through your profile the only potential shortcoming I see is, looking at only a few threads. Find a couple more topics to look at, and the new-user restrictions should be lifted.
Oops - I see your 2nd post in this thread was flagged. Was that a spanking from the automated spam cop? The post's content looks OK to me.
If the restrictions aren't lifted soon, message one of the admins and ask why. I think @ChrisGammell, @Joan_Sparky and @davidsrsb are admins - there are probably others.
