Cool, but looks like you've got a classic chicken and egg problem here. No posts, no users. Might be a good idea to recruit some friends to do some Q&A?<p>EDIT: I tried to register - I think your Captcha thingy is broken because I tried about 10 times and failed.
You seem to have a lot of topics without a lot of posts. May I suggest consolidating the topics until there is enough activity to justify the fine-grained classification? It might simultaneously improve focus and reduce maintenance workload.
