I need contest ideas.
 

The photographer for my website was kind enough to donate a shitload of Nintendo Ds game systems, Xbox games/accessories, and a bunch of other cool crap to give away as prizes on my site - I just need to think of the best way to do it! Obviously if I'm going to be giving away prizes on my site I either want them to a) up the content on my site or b) help increase membership. Has anybody done this kind of thing before?

My site is an alt-porn site focused on gamers/anime fans/nerds in general, and it focuses really heavily on community and stuff like that. I had a few ideas but don't know how easy any of them would be to implement:

1. Referral contest - Whoever could get the most number of people registered on the site. The forums don't have any way to track this, so it would have to go down where members who sign up would post in a thread saying who referred them and I would check the IP to make sure they aren't the same person. This would be beneficial because you wouldn't need to get anyone to actually sign up to the paid portion of the site

OR

People participating through sign up for affiliate/referral membership through our payment provider, Zombaio.

2. "Scavenger hunt" advertising. We offer flyers for you to print out, and you post them around various places that we have off a list (ie game store, book store, etc) and take a photo posing with it. Or possibly work it so whoever wins "most creative advertising of Pixel Vixens" would win.

3. User submitted photo sets. We could start a fan submitted content portion of the site, with each set being entered to win a prize. (I know this would be a pain in the ass because I would have to get both releases and 2257 forms from everyone who enters)

Anyone else have any other good ideas, or have any experience actually doing contests like this?

This is an interesting idea. I've never heard of such thing I believe. Can it be successful? Well, I would think that Porno Advertising can only be placed in an Adult (18+) context. Good luck with that. I mean you can't advertise porno in mainstream stores, right? But, you can advertise it in porno stores.

Wow .. Interest ..

i want a system!

#3 sounds good, each pic or vid would need to show one of your flyers or something to prove its real. Not sure about releases and 2257 forms, how do all these amatuer sites and forums do it with all the user submitted content...

I've seen many times when joining forums it asks if/who reffered from, but not all new members would click if its optional. Maybe a simple script with members username could be implemented to track this.

#2 is great idea, most creative advertising and most daring, members could create their own or use your flyers, or whatever they wanna do to be most creative or most daring, like plastering their car with flyers for a week, writing the logo on their ass and showing it in a police station, or go to a church and when the happy new couple are having the family pics taken outside run in front and do a moony with logo on ass.
I'm sure your surfers will come up with some great ideas for the chance of free nintendos and stuff.
You could have each member start a new thread with their entry, then the top 10 threads with most comments goes into a final poll.

Let us know when it starts, should be fun checking out, good luck.
