To enter the raffle, you need an email address or a facebook account.
Then to complete your entry, you must either visit (open the page) their facebook site or tweet about the raffle.
This is such a good idea!
I think this is a good model to follow for other bts projects.
Can we incentivize SEO with raffles? Or will that cause problems with google and de-rank bts?
Bts branding looks really good!
