Educate me more in this community

I am Antwi Gabriel, i just heard about steemit about some days ago and i sign up to this community today with the name @gabbi-bg.

I have read so many things concerning steemit and I was guide by @banapat to write my achievement post.

I heard this is a learning community that will help you in writing articles and posting them to earn a steemit.
Browsing through, I find out "Question, answers and comments" under talk channel which I think will be very helpful to me because I trust that noble people of this community will help me.

Honourable members, help me by answering the following questions for me.

1. After achievement1 post what next?
2. Is there any achievement post again?
3. How do I earn with my post?
4. After posting my article, what other duty is there for to make my community enjoyable.
5. How do I even invite friends to a challenge?

I believe and trust you that you will help me out.
