##      Description:  This mod comes together with the Plugin AP_user_statistics and
##                    one does not make any sense without the other! 
##                    For your convenience the plugin file AP_user_statistics.php
##                    is included with this mod.
##                    It allows the Administrator to see statistics for: 
##                    - How many and which users visited in a certain period
##                    - Which topics they saw
##                    - The total number of visits per day for a given period
##                    - The most read topics for a given period
##
##   Affected files:  functions.php
##                    viewtopic.php
##
##       Affects DB:  Yes
##
##            Notes:  1. The install_mod routine currently works only for MySQL.
##                    2. The table YOURBOARDstatviews_all can become pretty big
##                       depending on how many registered users visit your board.
##                       It has to be cleaned up manually unless I decide to add 
##                       a routine for it (or somebody else does) ;-)
##                    3. As long as your statistics tables in the database are not filled
##                       with user entries you will of course receive some errors ;-)
##
##    Release Notes:  - Text Modifications in AP_USer_statistics.php
##                    - Nicer error messages when no matches are found to dismplay by the plugin 
##                    - Removed YOURBOARDstatviews_daily from the install_mod.php
##                      The routines behind it are not currently implemented.
