I have a myspace account with over 7000 Friends - mainly teens. So I am looking for the best ideas in monetizing this niche of teens. Or if anyone is interested in buying this account whats it worth?

Good luck--most teens on myspace ignore bulletins from people they don't personally know, because of the high rate of spam bulletins. Same goes for messages. You *might* be able to get a mediocre amount of traffic if you have a free porn site. Other than that...well...
