(validate plugin) (remote) How to bypass the positive 'remote' error and submit the form?

Hi there,

I'm currently developing a multi-choices question game where the player has to identify himself using his login and password to record his answers.
One feature of the game is to allow a player to play again so he can update his answers (yes, I want them to win).
Using the 'remote' feature of the 'validate' plugin, I can check if a player has already played and display a 'you already played' message.
But then, the form is lock because the positive 'remote' is considered as an error.

Is there a way to use the 'remote' feature but still allow the form to be submitted?
A kind of "yes, this is an error but forget it".

Thanks a lot
