Help with a few things!

Hello anyone reading!

I am starting a public pixelmon server and I have a few questions. My server is on 1.10.2 MC.

Firstly, I want to get rid of the “<>” in chat surrounding players’ usernames. I thought PEx could do it, but I cannot figure out how.

Secondly, is there a way I can disable downfall?

Thank you to anyone who replies!
