New Deck UI - There are new controls on "My Deck" that make Deck maintenance easier and more intuitive.
Messaging - You can now receive messages from people on your friends list even if you have refused private messages globally.
New Game Client - The new version of the client allows you to challenge and message other players with just one click. You can also play Urban Rivals in a popup. On the game page choose to play it in normal mode or in a small medium or large popup. Gameplay is the same, it just gives you more options and is very handy for people with small screens. If you have a popup blocker on your browser you may have to set www.urban-rivals.com in the list of allowed sites.
Darkmnemonic: unfortunatly, the clintz pack allow for a abuse of our system, it won't be coming back anytime soon.
Vanish: it would allow a admin to takeover a guild. We'll add a "creator" status in the future.
