great hack,
I know someone prob did this, but I was updating my forum with vb 2.3.2. and made this small template change if anyone is interested

works great

good job!
Edit: Template "forumdisplay_sepsai" change contents to:
Code:
<tr valign="top">
<td colspan="10" bgcolor="{tableheadbgcolor}"><img src="{imagesfolder}/clear.gif" alt="" width="1" height="1" /></td>
</tr>
basically I just added {tableheadbgcolor} with a bgcolor change, to make it fit any style

again I didn't read the whole post so not sure if someone did this or not, but hope it helps.
