## MOD Title: Timeout Mod 
## MOD Author: itst < sc@itst.org > (Sascha Carlin) http://www.itst.org/
## MOD Description: This mods allows guests to surf the forums for a predefined time.
##                  After this time runs out (a little countdown is shown in the header)
##                  they must either login or register. All other attempts to access the
##		    forums are redirected to a info page.
##
##		    All setting are done via constants.php. The text for the info page is
##		    set via lang_main.php.
##		    You don't need to use the shipped timeout.php. You can use any file
##		    you want, even a file outside phpBB.
