Since this is my first season on here, will somebody explain GDT to me? Can anyone start them? Should they? What are responsibilities if you do?

Go back and look at the 2016 GDTs for a sense of what it is.    Anyone can start one.    All ya gotta do is follow the "format" of startin' one.    Basically, it includes the lineups, broadcast info and occasionally the local weather.     Chief has a thread on starting a GDT.    Once you start the thread, all you gotta do is get the hell out of the way while the feeding frenzy takes place.
