I'm looking for people who want to teach with voluntary or free to help make my rank level up
It's nice that you're willing to improve, but "ranking up" shouldn't be your main motivation.
make quality post
That's easy: get an education (most (developed) people spend 15-20 years of their lives in school), and discuss subjects you know well.
Don't post hundreds of links to Twitter/Facebook, and don't

You're expecting instant results, that's not how learning works.
I hope I will found the teacher here to teach me voluntary. Thank you
Again, move (see bottom-left corner) this thread first. Lesson one passed!
Suggestion: how about you delete all your bad posts? I'm very curious to see which ones you'll delete, and how much will be left.
