ethereum wallet: safe to experiment testnet and store ETH on main network?

[metalbean]

Am playing with contracts on testnet but also storing ether on my main network. Am assuming this is safe and separated?

Any advice?

You should be fine but I would be sure you are running with 2 different private keys, one for main and one for test. This would be just to ensure you do not accidentally submit a transaction on the main net that you meant for the test net and lose anything. The main net would reject a transaction made with the test net key due to insufficient funds and keep your ETH safe.
