My bad. I figured I was going to do it so it was just a reminder. If you want to give it a shot:

Someone removed sirbot from #help this weekend and I only noticed it because there was a message posted. I didn't know user where able to do that. The goal of this issue is to notify the admin channel when the bot is removed from one.

We might need to subscribe to a new event and auto-rejoin would be the awesome but may not be possible
