 hn_htusers HISTORY
--------------------

Jarno Elonen created the original script and basic functions in 2004
Sarah King converted the functions to a class and built in user management routines in 2005
Horst Nogajski  - built in group-support and extra infos (both optional)
                - uses Apache-Style MD5-Cryption Passwords. Now works cross-platform (win,unix)!
                - built in CSS-Styles for more useability
                - built in Validation (min-max length, allowed Chars) for all entries
                - LockingMechanism is more robust. Needed, because now every user may
                  send (lots) requests resulting in writeaccess to the file(s), (password or info)
                - and some more 'hardening'
                - all in 2009
