Users have applied to WGT for (opinion) more important options for CCs, to no avail. Go figure :(
When I get a request from a player I have to consider what is more effective: Ask him if he might comply to my considerations of a supportive member of my CC before accepting him, or just let him pass and go to considerations afterwards(?)
My current procedure is the latter. Once I'm convinced that he/she will meet my one and only "hard" requirement (German language) I accept the user. It's easier to look at their record later to see if they are active, and if not they are expelled in the most friendly way - "freeing the space for active members".
I've only had one user who glistened with zero activity - he and a few other mayflys have left the CC involuntarily.
