If you're looking for a good upload spot, I've been suggesting people put their stuff into this Google Drive I made.

Wow, that was fast...already, we've had issues with people coming in and deleting things, even before very much has gone in there. I guess I was wrong to have a trust system.

Can't the VMT define multiple possible textures for one model? That's how TF2's two teams work, or something similar.

I'll start putting guards around the gold vault as soon as we have gold to put in. Right now, I don't even know if many people would notice or care; and with Google Drive's limited functionality, I don't think things like moderators can be appointed.
P.S. Link isn't working for anyone on mobile devices, not that you could do much there.

How exactly does this work? Does this basically just let you connect to each other in Game Mode somehow, to record multiple players interacting?

The "continuing story" thing is definitely fun, and many forum games start that way, but the tennis idea is to re-edit the original video. (It would probably look in some ways similar, and be about the same length, but with some unique personal twists of the person doing the "serve")

More lately I've seen a lot of Gmod and SFM videos that make use of all the sorts of classy sounds we might remember from Looney Tunes or other cartoons of the sort. I'm wondering what sound effects libraries other people have used - previously I've done "okay" at just searching various websites for the specific sound I know I need, but it almost seems like most of the great sound effects I hear in movies I couldn't really give a "name" to.

Random examples I can think of: The "slide" sound made by some instrument as someone pops their head up over something, or around a corner; a heavy "blink" sound made after something awkward is said; a "dash" sound as someone runs off, disappearing in a cloud of smoke (though it's not like I'm just looking for those 3 specifically)

Wow! Looking very good so far! I'm glad you've stuck with it to two minutes long.
I'm glad that as opposed to Garry's Mod, even old work can be touched up. The other guys have said some useful things, but I might say one thing that stuck out to me was the way the girl walked forward with her head down - if it's really a pleasant dream for him, she'd be looking up at his face the whole way, with bedroom-eyes, etc.

(I especially liked the sound effects for the heavy's smile - I keep meaning to look for those, myself)

Sounds like a great idea; I just feel sorry for the fact that on my schedule, I'd never be able to grind down and make a movie, even a small one, in one week (when I get an idea, I tend to want to take it all the way)

This is a kind of low idea but here goes...

YTP creators often have "tennis" matches where one of them posts a dumb video. Then, the other re-edits that video with more zany effects, often adding some new source or element to it or tweaking the sentence-mixing. This goes back and forth until the video is unrecognizable and makes no sense at all.

In SFM, you could have two reasonable animators creating dumb SFM videos, then sending the DMX file back between each other to see what the other person adds. It would be like YTP, but in high-quality CGI.
