I don't post random things in LOH Community. I just write a post when I see that their weekly contest has a prompt that interests me.
I would recommend having a read through the rules for each community and follow them as closely as you can.
It's not too tricky, just takes a little time and care. And over time you'll find the communities that suit you best and you'll find it easy to post in there without any issues.
You got this!
Yes, I will do that. Thank you again.
