[jQuery] [Validation] One request and one issue...please help?


I'm trying to do two things that seem as if they should be very simple
(for somebody who has a little more experience than me, that is):
1. Attach a pending label to a currently validating field, like the
error and checked labels
2. Prevent validation on a field with validation rule, but which is
optional and empty.
Can somebody help me with a concrete answer or a code example?
Thanks,
Rus
