You have to send them an email and tell them you donated for raffle tickets.Guess I missed out.
I just donated $50, and paid the transaction fees, but was not offered the opportunity to get raffle tickets.
Per the founder: Use the “donation” button, and follow up with a message to us with Name, # of tickets purchased, address (so we can mail your tickets), and phone number (so we can properly fill in the ticket stubs we keep to contact you when you win).
