I've been using (b2) and now WordPress for about a year, and since I've started, I've been using real names for my wife and daughter. Now, I'm rethinking that policy. So I'm trying to write a fairly simple hack, modeled on the smilies replacement function- that converts :) into an image. I set up an array of b2pseudonyms in the config file, but looking at the function file I can't see how to "add a filter that displays a psudonym for each existence of the name." I'm sure I'm missing something on how "add_filter" works; could someone enlighten me?
