MyBB Community Forums

Hello guys. I am now coming to this world MyBB, and I'm trying to change the posting style. Is there a tutorial to teach it?

I'm developing a forum to my school, I would do something different in the post style. More or less as shown in the image.

can you elaborate your requirement in words ..
if you need to change thread posting style then you can use XThreads plugin
