Hi Kelley,
I think this might be the paragraph you are looking for, from the overview page of the blogging contests forum page,
Silver members are welcome to enter
Anyone can enter these contests but the ability to win the paid writing assignment is restricted to Gold or Platinum members. Silver members might want to enter to see how they stack up against others. Silver members who win will receive a one year paid Gold membership. However the paid writing assignment will go to the highest ranked Gold or Platinum member. Silver members who do win and receive a one year Gold membership, will be able to win writing assignments on future contests under their newly upgraded membership.This rule can be altered or modified at the discretion of the owners of FaithWriters.
From reading this I don't think there is going to be a silver member winning each time. Rather there will be 3 winners,
but if 1st or 2nd place is awarded to a silver member, they will be given a 1 year gold membership instead of the paid writing assignment, which would then be given to the next ranked gold membership holder.
I hope that clarifies things for you, and if anyone else has any other/different thoughts perhaps they can also comment.
Blessings, Helen
