Charlie,
Try to not count the votes of people with multiple log on names...or those who alread rank for another magazine or web site. That should greatly limit your work. If you do or do not allow people to vote on courses where they are a member or have a finacial interest, past or present, is also up to you. The best way around the above problems is to require a green fee payment stub accompany each vote.
Best course I ever played and payed where I don't have a relationship with the architect or undue worship thereof...Torrey Pines South.
