One of the expectations of being a staff member is to be professional. He isn't really doing it to impress anyone nor trying to gain a promotion. He is simply just following the rules.Because it's obviously being done because he's a staff member and trying to impress the admins. There isn't a need for that.
You are entitled to your own opinions of course but I don't think that should be an excuse to bash TL about his professional message, and that is my own opinion.While it is, that's unnecessary. This is a community based forum and it's not meant for two people. It should be more casual and that's my opinion
