I guess that I will validate the entries server side.
there are many issue using the validation plugin.
If the form contains errors and then you decide to close the modal window, if you reopen it the errors are still there.
Unfortunately I’m a newbie in JS stuff and cannot help you more with this.
On a side note, you should post your plugin on the official jsuery site. This is the most powerful i’ve found.
Congrats.
