Ok in the interests of keeping the momentum going i shall suggest a format.
Game opens at the beginning of the month, at this point a topic or theme (the "challenge") is put forward.
For the next two weeks the post is open for submissions.
After two weeks a poll is erected (GIGIDY!).
Polling closes one week after it opens.
he or she with the most votes wins, and is then in possession of all the kudos.
The winner then presents the next challlange at the start of the next month.
So in summary:
2 weeks writing.
1 week comment, feedback and voting.
1 week downtime, during which the winner choses the next challange.
Seem good? Any refinments?
