How can I add a location/address/business that BrightKite cannot find?

For example, i was at a cafe and when i typed in the address it said it could not be found. I would like to see functionality that allows users to add businesses based on address.

Additionally, I entered in an address to check in to and BK gave me the wrong business name. How can I correct this? Also, where are you pulling your address data from?

Thanks!
