I would like to participate. However, I think it's a better promotion to just straight up divide up the 500 PGAI to 5 people. The more the winners the better and wether you win $500 or $5000 you'll be extremely hyped. I even feel you could do a $50 giveaway to 100 people.
But that's just me. I followed though :)
You advice has a great value for us. Check campaign b :)
