About a month ago I was putzing around with the moderator functions in chat and booted two people. I didn't give it another thought because not all the functions are active. A week later one PMed me and asked if I knew when chat was going to be brought back because he hadn't been able to get in for a week. Oops!
So that was going to be my plan for those who wanted it to go away: bring them into the chat and boot them. They still have full access to the forum but no chat.
To get them back I had to drag their icon into the chat window to "invite" them back. Let me know, Ron, if you want in.
