Slight correction to the install file:

Step 12 should read: In pm_messagelist_periodgroup find
(not PM_MESSAGELISTBIT_IGNORE)

And the code to search for in step 12 is:

	<tr>
		<td class="alt2" colspan="<if condition="$show['pmicons']">3<else />2</if>" style="padding-top:3px; padding-bottom:3px; border-bottom:1px outset; cursor:pointer;" ondblclick="toggle_collapse('pmf$groupid')" width="100%">
			<div class="smallfont">
				<span style="float:$stylevar[right]">
					<label for="checkall_$groupid">$vbphrase[messages]: <strong>$messagesingroup</strong></label>
				</span>
				<a href="#top" onclick="return toggle_collapse('pmf$groupid')"><img class="inlineimg" id="collapseimg_pmf$groupid" src="$stylevar[imgdir_button]/collapse_alt{$collapseimg_groupid}.gif" alt="" border="0" /></a>
				&nbsp;
				<strong>$groupname</strong>
			</div>
		</td>
		<td class="alt2" style="padding:0px; border-bottom:1px outset" align="center"><input type="checkbox" id="checkall_$groupid" title="$vbphrase[select_deselect_all_in_time_period]" onclick="check_all_group(this, '$groupid')" /></td>
	</tr>

(You just forgot to include the <IF> for pmicons, no biggie, but might confuse someone)

I beleive that's all that was missing. Great mod, simple but powerful improvement to the private messages. Thanks Mark.
