A very very trivial matter...but for the sake of making the subforum links exactly identical to the regular forum links, I changed the line that starts with
$subs.= so that the forumid number and sessionhash were reversed. The stock vB has the sessionhash in the link first, followed by the forum specification...in this hack, it's backwards. As I said, it's trivial, I'm sure it makes no difference; I just like to have things looking the same, that's all.
PHP Code:
$subs.="<a href=\"forumdisplay.php?s=$session[sessionhash]&forumid=$forum_child[forumid]\">$forum_child[title]</a>";
