Enter and Vote = Go to the site and be able to submit your own link to the site.
Enter without voting = Go to the site and NOT be able to submit your link to the site.
I did more research and found out that "Votes" are counted when a person clicks on the Aardvarks Mini-banner, gets directed to the TopSites page, and then submits a link to the list. Each submitted link = 1 vote.
So basically, if FiestaFan (or any other Fiesta site) had an Aardvark mini-banner on the site and a person clicked on it, they would be directed to the TopSites page. Once there, IF they submit a link to the TopSite list, then FiestaFan (or whatever Fiesta site it is) gets a vote. The Aardvarks TopSite mini-banner has a code that makes it so that it will detect where the person is coming from so it will know if the person is coming from FiestaFan or not and it will give the vote to FiestaFan.
So, the more submitted sites, the more votes!
But, as of right now, the Fiesta TopSites list is configurated so that votes don't matter. Sites are ranked by amount of pageviews it gets.
Pretty soon, I'll be editing the layout of the TopSites page so that it will show a site's rating and the number of votes it has received.
