I'm thinking there would have to be a co=ordinator who would perhaps take the names and addys of people who want to have an angel, and those who want to be an angel could contact them to get the information. By signing up to have an angel, they would be giving permission for their address and other info to be given out.
Perhaps on signing up, each one could give some info like what they like to make, color preferences if any, and their skill level, etc.
Just a thought on how this might work.
Otherwise I guess you could pick someone you have already had an exchange with and just not tell them it's you. Since if you have exchanged already, you would have their info.
Patrice, any thoughts on this?
