I'd like to see some sort of privacy protection in not only Mirc, but the whole of Irc itself. Anytime a user gets on Irc, the /who and /whois commands expose him to every freak that wants to get his/her information. This is a serious security hole which can lead anyone right to your doorstep! I think we have come to a point where the only ones who should know what your IP is, and anything else about you are the Server Security (IrcCops and Admins)- not even channel OPs should get your IP (anyone can be a channel OP, who knows how many mass murderers are out there collecting your info for their little "list"). Channel OPs should get a unique username and that's it. They can still do whatever they need to do (kick, ban or whatever) but there shouldn't be access to your IP. There is no valid reason why everyone who gets on Irc has to give up their privacy to any nut who wants to get info on them.
So I hope for a feature that will protect user's private information from prying eyes.
