I realize this question has already been addressed several times:

http://bbpress.org/forums/topic/extra-dropdown-field-in-registration-page

http://bbpress.org/forums/topic/create-a-text-area-or-drop-down-in-the-user-registration-signup

Still can’t seem to find an answer. Happy to pay for a solution to add additional custom dropdown fields to the bbpress registration form, if still no solutions have been offered up by the community. email me at pdvailla [a] yahoo [dt] com if interested.

More than happy to share solution as well, since many folks have requested this.

Decided to abandon this approach. Now using deep integration and handling all accounts in wordpress, in order to easily customize registration.
