Jason Tourtelotte (major refinement to the code -- almost a complete rewrite)

Description


This modification adds the ability to show an index listing of pages that start with a certain letter. There is also an alphabetical heading at the top of each listing. Just click a letter to see pages that start with that letter.

For example:

Usage:

{{pageindex letter="d"}}


Outcome:

Page Index


This is an alphabetical list of pages you can read on this server.
