How do I ignore this URL?

[Andrew Ittner]

On a web forum's main page, there is a URL that keeps triggering the
diff, so every day the page gets delivered.

The line in question:

<b>209074</b> Posts in <b>15489</b> Topics by <b>13340</b> Members /
Latest Member: <b> <a
href="http://forum.example.org/index.php?action=profile;u=123";>exampleus
er</a></b>

"exampleuser" always triggers the diff, I cannot determine how to get
websec to ignore it.  The rest of the line is ignored, as it matches the
[Forums] section.

My ignore.list:

[Forums]
#\d+ Posts in \d+ Topics by \d+ Members.*
#Posts in \d+ Topics
Members / Latest Member
# ignore any stand-alone number
\d+

[ForumURLs]
# ignore member URLs:
http://forum.example.org/index.php?action=profile;u=14173
http://forum.example.org/index.php\?action=profile.*

And the subscription in url.list:

URL = http://forum.example.org/index.php?board=65.0
Name = Example forum
Prefix = example-forum
Ignore = Date_Time,Forums
IgnoreURL = ForumURLs

What should I change?

Thanks,

Andrew
