Comments in SEO Mod?

The comments comment our blocks of code, and are necessary.

The phpbb team asked me to do inline finds instead and I'll note the changes that way in the future but they are commented for a reason.

Comments
I know a lot of your comments get rid of code, but I think there's other sections that just add comments with no changes. For instance, the very last instruction in the installation file says this:

#
#-----[ FIND ]------------------------------------------

<table width="100%" cellpadding="3" cellspacing="1" border="0" class="forumline">
<tr>
<td class="catHead" colspan="2" height="28"><span class="cattitle"><a href="{U_VIEWONLINE}" class="cattitle">{L_WHO_IS_ONLINE}</a></span></td>
</tr>
<tr>
<td class="row1" align="center" valign="middle" rowspan="2"><img src="templates/subSilver/images/whosonline.gif" alt="{L_WHO_IS_ONLINE}" /></td>
<td class="row1" align="left" width="100%"><span class="gensmall">{TOTAL_POSTS}<br />{TOTAL_USERS}<br />{NEWEST_USER}</span>

<tr>
<td class="row1" align="left"><span class="gensmall">{TOTAL_USERS_ONLINE}   [ {L_WHOSONLINE_ADMIN} ]   [ {L_WHOSONLINE_MOD} ]<br />{RECORD_USERS}<br />{LOGGED_IN_USER_LIST}</span></td>
</tr>
</table>

<table width="100%" cellpadding="1" cellspacing="1" border="0">

<table width="100%" cellpadding="3" cellspacing="1" border="0" class="forumline">

<table width="100%" cellpadding="1" cellspacing="1" border="0">

<!-- END switch_user_logged_in -->

I've looked over this code line by line, and I can't see any changes. Am I missing something? Thanks!

It adds the user logged in switches. Those are not comments but rather instructions for dynamic display. That means that block will be displayed only if the user is logged in.
