If it's alright, I do have a quick question. The install file for this mod is....interesting to say the least.
Most install files will tell you to find a specific line and tell you what text you are looking for. The very first line to look for in this install file reads like this:
#---------[ 4. OPEN ]---------------------------------------------------------
#
header.php
#
#---------[ 5. FIND (line: 176) ]---------------------------------------------
#
else
#
#---------[ 6. BEFORE, ADD ]--------------------------------------------------
#
// MOD: MARK TOPICS AS READ - 2 LINES NEW CODE FOLLOW
else if (basename($_SERVER['PHP_SELF']) == 'viewforum.php')
$tpl_temp .= '</ul>'."\n\t\t\t".'<p class="conr"><a href="misc.php?action=markforumread&id='.$id.'">'.$lang_common['Mark forum as read'].'</a></p>'."\n\t\t\t".'<div class="clearer"></div>'."\n\t\t".'</div>';

That's great, but line 176 is supposed to just read, "else"? There's a lot of places that could just say else. My line 176 does not say else...line 173 does, but without any other clues as to what text this is supposed to go in front of, it does not help much. Just like elbekko said, some of line numbers will be different.
I'm not a php guru so I am a little hesitant to start dropping this code in and seeing what happens. I guess I shouldn't worry too much about it though and just try it out...but you all know what it's like to have mistakes happen and lose information on accident.
