Is it possible to get a Region name changed? I'm just wondering. I didn't submit a pe yet because I want to know if it is possible or not first. Thank you guys!

Yes it is possible. Although it is not always needed.

Is there a command I can do myself since I'm the owner of the Region, or do I have to submit a /pe?

You can get it changed but you would need to do a pe.

The only thing you can do is add members and remove members x

Okay. So adding members I know is /region addmember (player name). What is the key to delete a member? There's no members in my area yet save for me, but I'm just wondering for the future. Thank you so much for your help too! As soon as I finish with Uni today I'll be sure to submit a /pe.
