Game hosts not responding.
I have had a few GMs just flat out, go dark...when that happens , its 90% of the time , something bad has happedn, there is a Game on my list, the GM hasn't been there for almost 2 years?..she was having health issues..i hate to thing of why she stopped.
Now? if you are in a game, and you posted..and aren't getting any answers, even through there are posts popping up...Send a PM...give the GM a time frame to answer..if they don't answer, they might just not have the guts to tell you they don't want you in the game.
I have used PMs from both sides of the fence...as a plyer the GM is normally Busy..or has lost interest in the game, and just pops up now and then to post with a friend...'just in case' they want to start back up...as a GM, if a player goes dark, I will send PMs and wait, then cut them if they do not respond by the target date.
alla in all? this is a Hobby, a lot of folks are here to 'try it out"..then get bored and move on.
