I am a member of a couple of online communities and own a few forum/community licenses including Peerboard, Tribe etc as I have multiple sites.
Anyway, I just wanted to say I have always had a positive experience with Mikhail Larionov the owner of this platform. I am an LTD license owner, and he seems to care about his customers more than most saas owners. FYI, I am not an affiliate and I have nothing to gain. Here is something I shared on another forum.
If you want a good platform look at PeerBoard. The owners seems to genuinely want to help and values its customers whether they are LTD or not. That's just my experience. I think they will give Circle and Tribe a good run for their money.
