Thank you for being kind enough to answer.
I did go through the article but it still doesn't answer it clearly. I really wish things could be clearer. What I understood is that you can cross post as long as its your work and after 7 days.
I also found this which I really can't make much sense of
"Only cross-post your own post
Never cross-post your own post"

As far as the other account goes, I might have to use them for different purposes.

It would need a lot more digging before I get somewhere on this platform.
Would be checking out your posts closely. You write beautifully.
