Anyone can post topics. I just have been the only one to have done this so far. My only rule is they have to be relevant, and insightful. Basically, they have to be well written enough that anyone can read them and learn exactly what it's about and know the topic after reading. :)
I've only one question, any of the members can post new topics or only the creator (in this case you) are allowed to do that? And thanks i'd hope i can help =)
Other than that were a pretty new group, we basically answer any questions people may have they can post in the request discussion and we get back to them with answers. I put up new topics that may help answer questions that are pretty common among players. But feel free to do as you please it's nice to have new members :)
