How to get back id of the table Users in a new table

sorry for my English.
When I use "Registration" it creates me a new user.
I would want got back ID by the new user and to insert him(it) into my table "info_Users".

Thank's for your reply

Hi jmtdesing,

I had a dig in the code and it looks as though the User data is saved to $form->data['_PLUGINS_']['joomla_registration']

I think that this is an object (rather than an array) so $form->data['_PLUGINS_']['joomla_registration']->id should give you the new User id.

Thank you for the track that you gave me

best regard JM
