Vacation

The FAQ says that I can have someone else take turns for me if I go on vacation. Is there some particular procedure for this, like a link I click that says they can take my turns, or is it just that I give them login information for my account? I suppose I'd be fine with that if that is how it is done, but I want to make sure I go about things the right way.
I didn't see any previous threads about this, at least none with vacation in them.
Thanks
