Hello, first post on the TF2C forums!
I've noticed that on lobby pages, the lobby chatbox will also contain messages from the TF2C console informing users (and more importantly, the lobby leader) about the state of the server password, rental time, etc. The way this message is presented I find problematic because it is presented as a message from "TF2Center", and someone can easily change their name to "TF2Center" and post incorrect and false messages, as was the case in a lobby I was in today;

I suggest changing the color of the text, similar to admins' text posts
