Sweetcapricorn: I thnk u must mention the day/date for ending of ths game othrwise how cn posts be ended.and secondly u are nt allowed in ths game coz ..obviously u win da game coz u knw da ending time nd duration of ur game

I think you got confused about rule

see example.
suppose this is my last post.
from now till 24 hours if no one will post and my this post will remain last till 24 hours then i will be winner.
there is no ending time, time starts from last post, if there s not any post within 24 hours, winner will be user with post.
Very simple - your post should remain last for 24 hours, if other post comes in between your post will be useless and time will start for that post.
