This is up to you, but I know of a message board that if you post a couple pics of your wife (or any hot girl no one knows and claim her to be your wife), she will have a great chance to win. Its "The Main Board" at rivals.com and people do this all the time on there and most often people win as well. You just have to get a 7 day free trial (no obligations) and start a thread on the main board which is under the football recruiting tab. The hotter the pics, the more votes you get and if your lucky (and the contest hasnt accounted for it), someone will set up a macro to automatically vote.
If you aren't comfortable posting pics of your wife or claiming a hot wife, just post a gazillion pics of insanely hot scantily clad women somewhere. If they are standard hot women pics from google images you wont get good results but trust me, if you REALLY want to win this is your best bet.
If you shoot me an email at email@example.com
ill even let you post under my name, but Ill have to see the pics beforehand (no perv) b/c this is a college football recruiting board and these guys will recognize any fraud and vote against your wife.
I know this is a lot of stuff, but I've seen it work dozens of times as long as you post pics b/c those are the rules.
