This plug-in will search a post and find names that match database records of people maked with the WP People Category 
in the XFN Links. When it finds a match, it will replace the name with a link to the person. There is a administration 
screen for adding people and their bios to the database viewing the current people marked for the filter. More than 
one person can be linked on a post. A individual name will only be linked once per post.
The original author of the hack stopped supporting it a while ago. I took his original idea and used another 
hack (acronymit) as a guide to make this work. The original worked with the my-hacks script used in 
WordPress 1.0.1, so this is beyond the functionality of the original.
If you were using the version 2 of Word Press People, then you will be able to see any current people in 
WP People and COPY them to the XFN database.
