The rules are in the 1st post. I had shown the previous years submissions to give everyone an idea of what others have done. However, hear are the answers your questions:
1.You must use some variation of: Stamp Community Forum, Stamp Community Family, www.stampcommunity.org,
SCF, etc. prominently in the design.
2.The designs will be displayed in an online poll for each member to vote for their favorite. There is only 1 vote allowed per member and the designs will be anonymous. Whomever has the most votes at the end of the voting period WINS.
3. The forum members are the judges.
Feel free to read the topic threads and polls from the 2009 issue, I think they are all listed under the CONTESTS, QUIZZES, & GIVEAWAY forum. I had bumped them up about a month ago with an edit. Look for 1st Annual Souvenir Sheet or something like that.
