1) Agree.
2) The "Don't do that" is Mint's, so you need to tell clout to get rid of it.
The multiple de-op thing is built in to Raggy, I can attempt to switch it off if you want me to. If it's not the Raggy one you're complaining about, I'm guessing its another of dn's ty things.
3) You need to speak to dn and ask him to remove them then. In my opinion you need to ask him to not op himself in the channel anyway. I don't op myself in channels I shouldn't, and neither should he.
4) Dunno about this one, I find some of them amusing, but then if you want rid of them then it's up to you and the other ops.
5) Clones are smurfing annoying, especially when they pretend to be 2 different people and have retarded conversations. I know I have 2 clients connected, but I have it that way for a valid reason. People who have more than 1 for s and giggles are annoying.

End of the day BoB, it's essentially your chat, so you need to tell people to turn stuff off it you don't want it there.
