Forums Scripts & Popups Could somebody help me with filtering script

Good day.

Well, i guess it would be filtering.

What i need is a simple script that could "catch" messages with say "XXX" + "YYY" in their bodies and then post them in a new specified window while making a pop up message in the tray when these messages are "catched".

Im a complete noob at this so any help would be greatly appreciated.
Or at least some hints.
Thank you in advance.
