Well new to the interlopers community at least haha
I've been toying about with the Source & GoldSRC engines on and off for a good 3 years this year.
I've lurked here numerous times (mainly the tutorial section) but I remember stumbling across some impressive work in the forums, the highlight of my visits being a user who managed to create a realistic-looking blizzard effect in the source engine.
So yeah, hello guys- I hope to contribute my knowledge & work to this site soon!
