Hello Thanhdt300,
I'm Minecraftnerd I can help u with MC things and give advice when you need it.
To answer your question I have some tips. They are listed below.
Post frequently (I do weekly.)
Be nice, understanding and caring
Help your peeps (people) when you can. In other words give advice to people when you can.
Make good posts
Don't spam (unless post is for random things, only put related answers/comments on posts)
Be open to other's opinions
There's probs more, but that's all I can think of right now
Hope you enjoy using KT.
Bye for now girl/bro.
