What online communities have you managed in the past?

Currently building a Product Hunt community on Rock (space.new/w/2k5rz9o) to provide resources for people preparing a launch or those who want to stay in touch with the PH community after launching!

We just launched the SoLoyal Community (soloyal.co/community). It comes in response to a lot of inquiries that we were getting via email, and we felt that empowering our users to connect with one another would help them get answers quicker.
