Ok guys, a while ago I wrote a script for myself and some... umm... 'special friends' that will pick up all the current iPGN-Comp game details (only if you are playing of course) and launch your CS, set your name and rates and connect to the server. It will also tell you in console which team you are on.
First you'll need to download the script
here. Then extract it to your mIRC directory and type /load -rs iPGNauto.mrc in any IRC window. When you've done that an options dialog will appear which you need to fill in
properly.
Once you've joined a game and you receive the details, a dialog like the one below will appear (the pass will be correct of course). You can either choose to click 'OK' and it will launch then, or it will launch after 10 seconds.
Your CS will then open and you'll be connected to the server.
That's it! Props to Denneh/uni/iNode/
009 and others for helping with testing.
