 * Hi! Is there any way to make PESEL(polish national personal identity number) 
   field unrepetable, so when someone is registering and if this field already contains
   such data, it will display error.

 * The easiest way to do this is in the plugin settings under the “signup Form” 
   tab. Set the “Duplicate Record Check Field” to your id number, then set “Duplicate
   Record Preference” to show an error if there is a matching record in the database.
