I thought I had posted something here, but it’s not showing up. ARGH! Anyway, I like Sheridan. He’s a good moderator and site technician. I never thought about inviting him to take a break from modly duties to join a group, but if he’s interested then he’s totally welcome to join. All my groups are public.
I haven’t specifically invited him, but he’s always been great about replying to questions or commenting, so I still get to interact with him. I do think it’s a good idea, because that gives him a chance to be “social” and not just work.
