When a posting has been submitted the poster (*/cgi-bin/user/fo_posting.pl)
echos the posting content, displaying its own URL.
But if this posting contains a [link:] structure using a relative URL (e. g. "?m=125756&t=24136"),
thus adressing a posting relatively to the forum main file ("index.shtml?...") , which works well while
navigating within postings this link now is interpreted relatively to the URL of fo_posting.pl,
thus resulting in a broken link. (Same problem as with the old Matt Wright forum, by the way. ;-)
(severity: low, as only this "echo mode" displays the broken link and normal forum operation is not
harmed.)
