To send coins is very straight forward.
If you are sending these coins to a friend, exchange or business, then all you will need is their Receive address (known as a deposit address on exchanges).

If your wallet is encrypted, which hopefully it is, you will also need to have your passphrase (encryption phrase) ready as this is required every time you want to send coins out of your wallet.

Pay To: Enter the OTOCASH address of your friend/exchange or business. (These addresses will also be stored in your built-in address book, where you can label or re-label whenever you wish)
