I've been using browser-solidity to test out my contract online. Usually I click "create" and then I can call all of my functions to test them.

However, I clicked the "publish" button, and I got a message saying "Metadata published successfully." What does this mean? I should note that when I did this, my MetaMask extension was connected to the public main net.

If I learn what's actually going on here, does that mean I can use browser-solidity to deploy my contract to a testnet for testing? I didn't get any address for where it was deployed or anything, just the message from above.

Thanks!

The publish button pushes the Metadata of the smart contract to swarm. This can be used to automatically verify the source code of a smart contract or to retrieve the web3 Json interface without having to copy-paste. It is not yet widely supported, though.

Concerning the second part of your question: Yes, you can deploy your contract to a testnet or even the public net. You have to change "environment" to "injected web3" and then it will just connect through metamask.
