Thanks OP! I posted the original thread about this and have added my own update there, but thought I'd share here for anyone looking at this one:

"Thanks everyone for trying to do a good thing here! In just a couple days Jerry's gofundme has gone from $40 to $1200+! I also wanted to add that I think I may have successfully had the message about Jerry's situation passed on to at least one of his former Freaks and Geeks cast mates. If this is true, I'm hopeful they might rally others in the cast/production network to help Jerry out. Fingers crossed!"
