Current Location in Gmail Signatures

Gmail users who travel frequently will simply love this. You can now instruct Gmail to automatically add your current geographic location to all your outgoing email messages so that recipients get to know where you are at the moment.

Gmail takes the IP address of the computer from where you are sending that email and uses it to determine the city / state / country from where you are writing that email.

How to Do ?

Go to Settings-->Labs, there check for below feature and enable it

Then Go to General tab under Settings and check the below option.

That;s it . Next time location with the State name will be appended to all your outgoing mails.
