I'm a newbie in using the ethereum wallet.

After I completely installed and downloaded data for the testnet I create a new account but my new account has nothing (0.00 Eth).

It lead to I can't do anything by this account. I try to create a new contract but it is hopeless (`the account you want to send from is empty`).

Please help me create a new account (temporary with a little Ether) for the testnet. 

I'm using the _Etherum Wallet_ and deploy the contract with the UI. Please, give me some instructions for this.
