I finally updated it, now you can pick 2 more maps (surf_kitsune and surf_rebel_resistance) and chat with other players.
You can use /sl to change the server, or if you want to change the map in your current server use /nominate and pick the map you want and then /rtv to rock the vote, if you're playing alone this will immediately start a vote for the next map and pick your nominated map by using the scroll wheel and left click.
If other players annoy you, do /hide or /show if you change your mind.
