Thanks, DCM. I'll give it a go.

Saw your post on the Discussion group(Some silly moderator locked it):

In most Valve games:
turn on the dev console
toggle said console with ~
turn on legit cheats sv_cheats 1 (never use an external program to do the cheating... bad things happen)
adjust gravity sv_gravity 200 (I think it starts at 800)
you can also make it negative
you can also bind that to keys... so when you feel like goofing off you can adjust it quickly with single buttons.

and if you're goind down this route, set sv_friction to some negative number. Enjoy!

If you're talking about other games just google it

Will do.

Aight, invite me when I'm online.
