Discussion about rules normally takes place on snort-sigs, so you guys
probably aren't following the discussion on this rule over there.

In short, the current revision of the rule is 3 and it is now in
deleted.rules.

The rule will appear in the deleted.rules for registered users when
they can download the rules released on October 5th. In the meantime,
might as well move it there yourselves.
