As of today January 1st, the monthly contest terms will be slightly modified.
Previously:
Whoever ranked in the top 3 spots were contest winners. Winners were based solely on the top 3 rankings in the total forum statistics.
Now:
The winners will be top 3 referrers compared to the previous month. Which means it is possible for there to be a winner who is actually not ranked in the top 3 in the total forum referral statistics. Everything else stays the same. So every month a member's referral count will be compared to their previous month's count. This numerical difference will be used to determine winners. See the modified terms in the 1st post for details.
Reasons for the change:
1) It encourages new members to participate. As it was before, a new member would join the forum and see that members who rank 1-3 already have hundreds of referrals. It would take too long for this new member to catch up to these numbers. So new members were discouraged from participating.
2) The new way acts like a monthly 'reset'. This puts all members on a level playing field, instead of the members with the top 3 rankings having an advantage.
3) Some members have previously understood the terms in this new way actually. And some have voiced their dislike for the old way. So the new contest terms may be considered fair and more widely accepted now.
