I got banned from joining mumble required lobbies.
Yet I am in every Mumble even if there not mumble required.
I find that most the lobbies I've been playing are mine, and they are mumble required and of course I am going to join it.
Having almost 700 lobbies I think I at least deserve to be able to join mumble required lobbies stating that I actually join them.
Not having the ability to join mumble is ruining most of the tf2center experience for me.
