It's also important not to take too much control as a channel operator or to make sure any ops you take on are not too controlling either. People are there to chat and not to be pushed around. People can quite easily /part your channel to get away from a bossy user with ops and they will do it without a doubt.

Don't overly instruct users to talk or bring friends in either. Try and let things develop by themselves. Your patience will pay off, I promise.
