Rules Dev is for the development of drools, not for questions about the 
use of drools. Please ask this on the user mailing list, which is 
detailed in the link below. Please also read the 17 netiquette points.
http://www.jboss.org/drools/lists.html
"The user mailing list is for general user querries about drools and how 
to use and it problems with using it. The dev mailing list is for more 
hard core discussions about about developing drools itself and general 
rules/ai theory that might apply to future drools features."
