I don't think mIRC should save server passwords. Scenario: i connect to a server protected by a password (using the "/server host port password" command), close mIRC, then someone else comes, starts mIRC, turns debug on and hits the Connect button. Need I say more?

in addition: You don't even have to (re)start mIRC to find the password, nor do you have to close it to have mIRC save said password. Once the /server command is issued the password can be found in mirc.ini -> mirc -> host (in plain text no less, granted standard IRC servers offer no method of sending encoded passes).

Would be nice to have mIRC only keep this information in memory.
