What is address?

It's just a shortcut to the public key. Once your public key is on the blockchain, you will receive coins using small address, instead of use the large public key.

Example:

publicKey: MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAEiCEOTeXDzM8lDlj21vmzQxzu9w6aN8f98uq3fSBwBQtL627QBvH0Rk8xsT9leiYtByp815SNPEcxS0cFXEm4IA==

address: A1B2C3

You can use (to send 1 mbtc):

/send 1 A1B2C3 

Or (IF the publickey is not in the blockchain yet.)

/send 1 MFYwEAYHKoZIzj0CAQYFK4EEAAoDQgAEiCEOTeXDzM8lDlj21vmzQxzu9w6aN8f98uq3fSBwBQtL627QBvH0Rk8xsT9leiYtByp815SNPEcxS0cFXEm4IA==

More than 4 billions of possible addresses.
