As i said i want to be a part of this community so i delete all my "lotto" posts.
Just take your time and prepare a proper lotto game. Make sure you have someone for escrow. Contact 2GOOD if you know him. A Hero Member vouching for you goes a long way. Also make sure people can understand how you pick a winner and can make sure that you can not cheat. E.g. let the lottery run for a week and the hash of the closest block on sunday 01:00 GMT will be converted in a certain way. If everyone can calculate the same number no one can cheat.
