File types
So I've gotten into the habit of downloading a lot of custom maps lately, because it really adds that replay-ability to the game which it didn't have before. I can play single player maps fine, just putting the .bsp file into the correct folder.
Where do I put the demo (DEM) files?
And, also, I'v been trying out doing custom multiplayer maps, where both me and my partner have the maps, and when I'm Atlas I type change level "mapname" into the menu but it just drops both of us. What's the problem?
What do I do?

Hopefully someone else can help you out with your co-op issue, as I haven't played coop at all yet.
What do I do?
Open the console and type "changelevel nameofmap" with out the quotes. You have the be the host (Atlas) for this to work.
