@dev, asides from the normal weekly airdrop, will I get extra mtnc if I wear mtnc signature on my profile and be active on the forum ??
No, look in the OP: Signature Campaign is over and closed
But see the airdrop rules:
We will offer extra bounty for 5 members who have special contribution after second round airdrop (2000 MTNC member) [including republish or help to promotion or make video or keep active in this thread or sth else]
