Follow the above instructions but use this line in the "Matching Expression" box:
<table border="0" cellpadding="1" cellspacing="0" width="97%">*<b>timbox129</b>[br]*<img src="i/dominant/trans.gif" border="0" height="2" width="1">[br]
You need to manually change the square brackets in the two instances of [br] above to HTML-style braces < >
Bye bye tim.
Although I doubt this'll be needed soon as the sock timbox seems to be on a mission to get itself banned.
