i dont want to risk applying more than once, so I want verify, do I still send my address and other info like we did in airdrop 3 to the dev via reddit? or that application covers airdrop distro 4?
You have to PM the dev here on BCT with your address, the number of posts at the time of applying, and whether you want to add the signature and/or the avatar until this round ends.
I don't think there will be a spreadsheet this time as you have proof of participation in form of the PM you sent to the dev.
