I think you need something like 100 posts (and not just "bump" or one-liners), plus having been am ember for a certain amount of time (I forget the exact quantity). You've been around nearly a year, but with only 17 posts, not a very active year. I was pretty much the same way for the first few months after I joined, but then I started joining in on discussions, giving answers and opinions on the "help" threads, and giving constructive criticisms, comments, or advise on build threads (I haven't built any armor yet, but I do have paint experience that I've been sharing). Find some builds that catch your eye or people working on similar projects to brainstorm with and talk about any problems they've run into that you should look out for, etc.. Once you start joining into the conversations more instead of just observing (which was my habit), you'll find the post count rising rather quickly.
