Thanks. I found an old test install where I had that hack done and it looks like you're exactly on track peterska2. It's slightly different, but I'm sure acheives the same thing:
Code:
<td <if condition="$bbuserinfo['pmunread'] > 0 AND $show['pmstats']">class="newpmblock"<else />class="alt2"</if> valign="top" nowrap="nowrap">
I looked through all my plugins and products on that test install and it's not there, so it must have just been a template hack.
