Contest plugin – Need your suggestions!

Hi there!

In all of WordPress world, there appears to be only two contest plugins: “Popularity Contest” and “And The Winner Is…”

Surely this can’t be true?

I need a simple system where people can enter to win contests, then have the site admin press a button that randomly shows the winners.

“And The Winner Is…” asks people to post a comment in order to enter — I’d rather they were able to simply click a big fat “Enter Contest” button instead. They shouldn’t be able to enter the contest more than once.

Do you know of any paid plugins that do this?

I’ve considered modifying the archive template to simply not display comments if it’s in the “Contest” category…

I’d also love for there to be some kind of “Thanks for entering! Good luck!” message appear if they’ve entered. Is there a WP variable that can check whether or not the user has already posted to a certain post?

That’s all my ideas. Let me know if you have any others. 🙂

Thanks!
