Literary magazine: A literary magazine is a periodical devoted to literature in a broad sense.

Consideration under American law: Consideration is the central concept in the common law of contracts and is required, in most cases, for a contract to be enforceable.  Consideration is the price one pays for another's promise.  It can take a number of forms: money, property, a promise, the doing of an act, or even refraining from doing an act.  In broad terms, if one agrees to do something he was not otherwise legally obligated to do, it may be said that he has given consideration.  For example, Jack agrees to sell his car to Jill for $100.  Jill's payment of $100 (or her promise to do so) is the consideration for Jack's promise to give Jill the car, and Jack's promise to give Jill the car is consideration for Jill's payment of $100.

Mighty Jill Off: Mighty Jill Off is a 2D platform independently developed freeware video game designed by Anna Anthropy, with art by James Harvey and music by Andrew Toups.

The struck plate, if present, would be supplied and fitted with the knocker.  Door knockers are often ornate, but may be no more than a simple fitting with a metal bob, or ring.
