For quite some time I've tried to get my own API Key for the translator on Ender's client.
I have finally found how so I decided to share it with the community. Here it goes:
Step 1.
Get a Google Account
Step 2.
Go to the Google APIs Console website and log in with your previously made Google Account.
Step 3.
Turn on Translate API.
Step 4.
Click on API Access.
Step 5.
Copy the key.
Step 6.
Open H&H and paste it on the Translation tab of the Client Options window.
Step 7.
Profit!
Congratulations, you now have your very own API Key.
