Social bounty program?
Yes, this is in the pipes, and it will definitely come soon !
You can now join Twitter campaign :
https://bitcointalk.org/index.php?topic=1950428.0 !
By the way, personal message and avatar have been added. The numerous members that joined the campaign and still have not applied the signture now have 72 hours to do so.
People that previously applied the signature correctly have one week to apply personal message and avatar when they are concerned.
To be fair for people that have done everything needed on time, anyone failing to meet those criterias will have to apply again if they want to participate in the signature campaign.
