##   Hack Title:    Active Link Referrer Blocker
##   Hack Version:  1.0.0
##   Author:        wd2004
##
##   Description:   This hack will block the referrer when a link
##                  is clicked by going through safeurl.de first.
##                  When ever a link is posted on the BB, it will
##                  automatically add the safeurl.de address to the
##                  link. The whole process is invisible since it is
##                  added to the main phpbb link processing functions.
##                  When you edit your post, the link will appear the
##                  same way as you posted it.
##
##   Compatibility: Tested on 2.0.10 only
## 
##   Installation Level: Easy 
##   Installation Time: ~1 minute

##   Author Notes:  After creating this hack, I have noticed that it was
##                  created already back in 2002. According to other users
##		    the previous version stopped working after phpBB 2.0.5.
##		    This version will work with 2.0.10 and maybe earlier. I
##		    would like to give credit to the original author of the
##		    first script "Safeurl Hack" by reimer. I would also like
##		    to give credit to safeurl.de for providing this great url
##		    protection service.
