New signatures are awesome! By the way, I have already changed it before the 15th airdrop, should we use the new ones for the 15th or the old ones? Just wanna be sure.
you could use either the old signature or the new one. it's up to you. both will still make you eligible for airdrop. just make sure that your reference link is linked to your bitcointalk id. you may try to click your links to verify that it's working well.
