I'm not sure if bugs in the PHP version should be reported here or on the bug reports board.
When you view postlist.php in expanded mode the "Posted on" data for replies to a thread show up in the "Views" column (Netscape 4.7 on Linux). This seems to be due to a missing </TD> as shown in red below:
<td align=center>&nbsp<font color=red></td></font color=red><td>10/24/00 07:34:23 PM</td>

P.S. Why does it have <td align="left" nowrap> around the "Posted on" date for the first post in a thread, but just <td> for the replies?
