I love the new Cometchat! I'm on the free plan, but my forum is small, so I shouldn't incur any fees for overage. Support is awesome, and I've been going back and forth with them this evening via e-mail. They have been replying within 20-30 minutes until my questions were fully answered.
The custom integration was very simple, once I carefully examined it. Everything works great, and the chat itself is 100% modern, and feature rich! Thanks!
