how do i find my steam ID???

Search here: http://stats.edgegamers.org/hlstats.php?mode=search&q=&st=player&game=

Or when you're ingame, press ` and type status. Then look for your nickname. Then look across for STEAM_X:X:XXXXXXXX

Open the developer console in any source game (I believe.) and simply type status. Search for your in-game name in the list that appears, and beside that will be your steam id.

I guess I'm just restating what Flux said, but just trying to help
