Micro-bounty offer.
Just a small idea for marketing activities at the coming "Inside Bitcoin" events. We could have a win/win lottery for collected business cards. Like every contact who left a card could receive say 20 NXT, and three of them could go up to 100, 500 or even 1000 NXT. This would attract interest.
Now the best proposal on how to arrange this with the least management (emailing back and forth, managing lists etc.) gets 50 NXT.
I too participate in this contest. My idea is that we "create" and top up accounts where the passphrase is their email. And Then we notify them to collect the monies and transfer them somewhere safe.
