These are 3 very small aliases I wrote, just for general use.

Command: /gnick
Version: 1.2
Author: XTZGZoReX

Command: /restart
Version: 1.0
Author: XTZGZoReX

Command: /reconnect
Version: 1.0
Author: XTZGZoReX

Usage of /gnick: Simply type /gnick and it will change your nickname on all active connections.

Usage of /restart: Type /restart followed by your quit message, and mIRC will quit all connections and restart.

Usage of /reconnect: Just type /reconnect followed by your quit message, and you will be reconnected to the server.

Enjoy!

alias gnick {
  if ( !$1 ) {
    echo -a * /gnick: insufficient parameters
  }
  else {
    scon -at1 !nick $1
  }
}

alias restart {
  scon -at1 !quit $1-
  exit -r
}

alias reconnect {
  if ( $server ) {
    quit $1-
    server $server
    halt
  }
  echo -a * /reconnect: not connected to server
}
