How To Use Greenscreens in SFM and GIMP

gave me the inspiration to do a greenscreen tutorial quite some time back, and practically made me finish working on it tonight...SO YES, FINALLY!!!  Here's a long-awaited tutorial on how to use greenscreens and edit them in GIMP.

If there's anything you've seen me do in my posters that you would like me to make a tutorial of, let me know!  And actually make me do it this time, otherwise I'll completely slack off on it like I did this one x.x

Greenscreen models for SFM can be found in the SFM workshop.

Why is doing this silly pose?  Educate yourself in the ways of Ace Ventura, you goof!!
