Questions about Mibba

This new layout is extremely confusing to me, so I have a few questions if anyone could answer me.

1. What does the little flag in the right of the blog boxes mean?

2. How do you add a new chapter to a story? I've lost it and now it wont come back :c

3. Where do you find out how many people read/subscribed to/etc to poems and stories?

I still don't have 100 words so:

My dog is the dumbest little nugget on the planet and I love him
He is also the biggest fur ball.
He's tiny, and actually really more like a cat. He sits in the windowsill when everybody is gone and prefers to cuddle with me rather than play.
His name is Koda, named after Brother Bear.

k thanks :3
