Hi, i'm a newbie and not able to attach a signature. Does that mean i cannot apply for the airdrop?

The signature is for junior member and above thus junior member and above is eligible for the main airdrop but good news to you visit the forum we also have DeepPoint airdrop which depends on your activities on the forum. You can participate in this till you reach junior member level.
if remember good just have a new rules said you need 1week old inscription to be elligible to airdrop deepPoint or something like that
but for now just 2way for you work here to have your jr member account and in community to learn about D.O and all opportunity offer .....
good luck was like you not so long.....
