New content is always great! For certain this kind of commitment makes me want to continue giving my business to the companies responsible. Thanks! You rock Star Dock! Which means Frogboy also rocks by default.
As for ban lists, I think the best way is a simple "/ban username" like squelchThe ban list should also be a text file so you can simply add the username into it manually while offline etc...
For consensus of ranked games... please just track all stats separately. Would it really be hard to show 3 sets of win/loss ratios and have 3 ladder ranks? The ranks have more meaning when applied to the context of where they were achieved.
You should also have a map maping contest when the SDK is released. The prize is you get to have your map officially included in the game if they are deemed worthy. (and credit in the readme file for being so awesome). If anything, 3rd party communites always show that there are several members capable of creating content that is the same quality as the developers.
