Sending mastercoin

[OTK47]

Right so quick question about Mastercoin. Once I have them sent to a dedicated address in my bitcoin wallet. How do I then send them from that particular address? I will be storing them on blockchain.info, is there an option to send coins from an individual address as have three in the wallet?

Thanks for the patience and sorry if this has been asked, can't find an answer.

Use the "Custom" option under Send Money.  Can choose which address to send from and also can add multiple addresses to send to in one transaction which you need to send mastercoin.
