Inn System? what is this?

Can some explain what this is? xD

You log out for a certain amount of time and basically the longer you're logged out, the more time you get for a certain exp increase. This is roughly how it works: You log out for two hours, you're then rewarded when you log back in with 30 minutes of free 2x exp. Of course all the variables could be different, but that's essentially the basics of it.
