There will be two gdm with two functions which are for info only and for convo.
May not chat on gdm INFO and may only chat on gdm convo when the position of the group name is "CONVO". GDM CONVO will be open on weekends and under certain circumstances.
It is strictly forbidden to break the convo and send random tweets to any gdm.
There is no limit to sending tweets to start a convo as long as the tweet you send contains the word invitation to chat but you must have replied to all other friend's convo invitations and don't forget to diving.
Breaking the convo gets a penalty.
