[rules-users] rules priority

[Nadav Hashimshony]

Thanks for the responses.
what i did was:

rule "Rule-01"
salience 100
activation-group "defender"
no-loop true
.....

rule "Rule-02"
activation-group "defender"
no-loop true
.....

this way i assured the higher priorities rules run first (salience 100) and
that only one rule overall will be used.

thanks.
Nadav.
