I am using the default user registration in Joomla with a minor modification to account for the users address for swapping purposes. I would like to pass this information on to each of the parties swapping items in the Ad Closed email.

1. Is there an easy way of field mapping using the default Joomla registration as opposed to the 3 options listed under Profile (Component Profile, Community Builder, Love Factory)?
2. What is the easiest way to reference the user information on a confirmed swap? That is, if UserA swaps ads with UserB, UserA receives the contact information (address, email, etc.) for UserB in the Ad Closed email and UserB receives the same information for UserA in their Ad Closed email.

I look forward to your response.
