Here are the variables commonly used in PM Bars, free for you to use for open source (credit would be nice, but not necessary).

Covers the basics to a PM Bar. Creates two different bars, one that a member views and one that guest views. Feel free to edit and redistribute or whatever you want to do with it. Try to study and learn how to use Regular Expressions and if/else Statements for making other codes and such.
