Is there a blog section here?
A lot of the forums I've been apart of the main landing page is comprised of blog posts, for example:
https://www.clublexus.com
It could be a place for unique build spotlights, meet recaps, general information ("Top 5 bolt-ons for your Hellcat" "How to boost your LS for under $1,500", ect. There is a ton of awesome information and builds on this forum, but they can get lost if you don't know where to look.
Blogs also help boost SEO quality and some choice keywords / titles could generate a lot of views from people searching on google.
This could also be done by multiple people (and should be really) so it wouldn't involve a ton of time or put more pressure just on Mook.
