I posted this question as well and didn't get an answer. Inevitably many of us will rank up as this airdrop proceeds. I don't want to risk changing the signature if it could potentially disqualify for future airdrops. Hopefullly we can get some clarification on this.
Another thing that has been urking me, I just signed up for the campaign this morning. I'm pretty close to the 10 required posts needed to receive the airdrop. Is it too late to receive this weeks airdrop by tommorow? I wonder how they keep track of it all? Hmmm
No that's fine, you the things that you need to be eligible for airdrop is:
1. Registered before 12 July 2017.
2. You're a Jr. Member.
3. Post 10 posts within 14 July - 21 July with minimum of 100 characters per post.
