Good point, I'll do that.

No, only one message per field can be defined. But that is a limitation
that seems to provide better usability anyway: It can be quite
frustrating to enter a value, get an error message, correct the value,
and getting a different error message. I think the better approach tells
the user what it expects with one message. You example could be written
as this:
$("#myform").validate({
rules: {
firstname: { required: true },
age: { number: true },
password: { rangeLength: [5, 32] }
},
messages {
password: {
rangeLength: "Please enter a password greater than {0} and
less then {1} characters long",
}
}
});

Mike offered to an option to the form plugin to directly pass the
validation settings to the form plugin. That would be the most
convienent approach.

Absolutely! The long-time goal of this library was to create a
serverside setup that generates the client-side rules based on the rules
checked on the serverside, so you don't have to duplicate them, just
what mentioned.
Please let me know when you implemented something, it would be great to
have some examples to do that in different languages.
