No, it doesn't at all, ever. Unless you'd like to explain how it does that?
I'm a responsible adult, not some snot-nosed kid. But you don't know for sure, so don't download anything just incase.
I Honestly believe that you are responsible with addon system and stuff, But im talking about auto update too? Nobody knows what it really does... (lol)
And about the mod manager, If was talking about the fact that it does upload scripts to a server, although indirectly.
If im right, all the files are just stored on a server and you can edit them.
Fox had an good idea, I'll make it so the host will need to approve the script before it gets run.
