As I'm going to be away for 3 weeks, I like to inform all my contacts that I'll not be around to answer their queries till such time. How do I set up a message in my Inbox informing them of my absence?

The answer meant to be helpful but did not understand the instruction which was & I quote 'go to gear on the right>more mail settings>manage your account>vacation reply'.  I cant find it to get the link for doing what the instruction suggested?
