1. In summary, just be helpful and constructively discuss with the people here in this forum. Don't spam.
2. No. But you could through signature campaigns, which you can't join as you just have a new account.
3. Through account activity + merits: https://bitcointalksearch.org/topic/merit-new-rank-requirements-2818350
In addition just continue to explore the forum since you where just a new member here and do some constructive posting, make a discussion with the other members from their you are going to learn a lot and potentially learn something that could bring you profit.
P.S. If you're solely here for the money, trust me. I'd genuinely suggest that you do something else instead, especially if you don't know much about Bitcoin and cryptocurrencies to start with. Bitcointalk is a forum where we talk about something we all love— Bitcoin. The earnings are just a bonus.
+1 just like what i said you could learn a lot here in the forum ask question etc. That might give you something.
