How many onions should a member expect bit nervous about messing this whole thing up any advise on how not to get banned
You can expect about 400 Onions for a member. Legendary members already get 800 and there were even people who got 3000 in the last Airdrop.
Make enough quality posts in both forums before applying, write a nice article about DO and don't mess up your signature, then you should be good to go.
