The growth is definitely impressive, there is no doubt about that. While there is a lot of information in here... it's mostly very general information that could be easily found elsewhere. It sounds like you have plenty of plans to be able to keep the members and the posts growing, I think that you need some authorities members to establish the legitimacy of the forums.
You've got a great name for yourself, and it's obviously been a huge part in the success of the site. But other than Lee, and one post by Aaron Wall, I haven't noticed any other big names. I think it would do wonders for the forums to get some big names in here posting some unique content that can't be found anywhere else.
I'm not trying to knock the forums at all, the growth is unheard-of within 6 days. Just offering my thoughts on what I think would improve the forums.
