Right now my forum has a couple active members, and one of them I'm really happy they decided to join my forum, because on another forum in my niche they have over 2500 posts. I don't want to lose my active members, so I've been doing more post exchanges, and engaging in the community more once this member joined. I have one other active member that checks in daily everyday too, and makes a few posts and threads. Everyone else is basically post exchangers or inactive members. How do you keep your active members happy on your forum when you're just starting to grow your community?
