1: This can only work if there is one party or one person who start the marketing, coordinates the marketing and gives away prizes
Who owns the official Ultracoin facebook page? Bumface? If so, he can.
2: There must be the willing in our community to make a free donation for the prizes to give away
We already know we have plenty of people who are willing going by how we got on MintPal with a lot of BTC votes.
3: There must be opened a promotional wallet in which everybody can do his/her free donation
I guess this is fine. Maybe we can trust Bumface with this if he wants to drive it.
If Bumface want to take point 1 and 2 on his shoulders I am willing to donate 500 UTC.
Now that's the spirit!
