This is the right thread, and if you want to use mods in public matches you need to add this code in the console as well:
Code:
party_connecttimeout 1
This will force you as the host. It will take some time to get a match started, because its waiting for people to connect to you, not the other way around.
Enjoy!
Oh, and make sure the mods folder looks like this:
Code:
\---mods
\---"Name of mod" <---This should be the mod folder
\---"Name of mod" <---This should be your .iwd file. Same name as folder!
