Unfortunately my bitcointalk account is registered in September 25, 2017 so I can not make an inscription to aidrop is that there is no new if they will accept the bitcointalk accounts saved after September 1, 2017 at next airdrop?
It's possible, they have changed the minimum required registration date before.
But we were not given notice, it just changed. So you should just stick around,
learn about the community, and when and if it changes you'll find out. Also,
joining the deeponion forum would be a good way to find out.
Being active before you actually have to be is, I would venture to guess, the
best thing you can do to recommend you for inclusion in airdrops. It shows
you're interested and involved, and aren't just going to dump and leave as
so many have already.
