The list of possible group leaders:
Nobody will be chosen against his will. Each group-leader-to-be will be first asked if he accepts the rank. ;-) Even then he can resign anytime he decides to.
These polls serve only as a popularity indicator. People you voted for most will be asked first.
Hmm, if you see yourself in the list above, you probably want to ask one important question. It'll be answered now:
The main and most important task of the group leader is simple: to keep the group alive! So the minimal input will be only un-linking offtopic texts (news, articles) and deleting inappropriate media, and electing new leaders if the present are inactive for more than 2 months (and they don't reply to e-mails/PMs). It's the minimal required contribution to the group.
The polls will be closed around the beginning of the new month (after a week).
4 new group leaders will be chosen.
