以前在用Movable Type 3.35版本的时候就有的
AutoLink provides users with a way of creating a list of "hot words." Whenever these words appear in a post, they are automatically linked to a designated URL. For example, if you were to frequently write about Movable Type, and anytime you mention the phrase "Movable Type" in a post you want it to be linked to http://www.movabletype.org/ without having to enter the link manually. This plugin will do that for you.
