Thanks for the review! The content amount issue is cause the install is pretty new, we were a read-only Wordpress site for a couple years, but now that we have a Forum, we're hoping to build upon that!
Activity level will increase as time goes on, of course, not much we can do in regards to that without doing some google ads or promotion on sites that allow it. (most subreddits have a rule against self promotion in the dinosaur niche)
As for the ads, I don't see them since I have ads turned off for staff and paid subs. But I could maybe limit it to one in the sidebar and and at top of forum list but not in-threads.
Thanks for your input, I'll look into that after my live stream soon!
