The current version includes use of the "Markdown" editing scheme for styling glossary definitions; soundex option in searching; numeric items grouped together; flexible configuration options.
I could not get this to work in Joomla 1.0.8 (Stable). Poor documentation. Also a suggestion, please clearly label downloads as "com_xx", "mod_xx", etc. this would be very helpful. Also, for a newbie it is confusing when the downloads refer to Mambo only and makes new users question if this really is a Joomla extension. Again, I could not get this one to work.
