It would be nice if player names were able to be listed by region. For Australians at least, this would mean knowing if there were players online of a certain 'calibre' to be worth making a lobby for.
On a side note, a system could be implemented to have players set a 'status' for themselves when on tf2c. By this I mean something like "Looking to play 6's" "Looking to play Highlander". Displaying these somewhere would also help people when to post what sort of lobbies.
