I need a script for a new site. It's a contest site and I want people to be able to register and submit something and then invite their friends to come and vote on it. I'd like to be able to reset the votes each month. I'd like to be able to have multiple categories. I want to use a CPA gateway for the voting page. I'd like people to be able to browse all of the categories and vote on other items if they want, not just the one they were invited to vote on. I'd appreciate any suggestions. Thanks!
