I would but the thing I dislike is that it's just the same 3-5 users on this site. Not that the 3-5 users aren't great or anything, I just prefer a more diverse and full forum to engage in.
Invite people. More people posting, the people who will start posting. This is definitely an issue with smaller sites. Not enough activity, but you just gotta keep being active and the site overall will become more so.
That's the theory anyway.
