[Plugin: RSVPmaker] Sign-in on account name?

Version 2.7 allows you to prompt users to login when they RSVP. By default, this autofills the RSVP form with their first name, last name, and email address.

To do what you have in mind would require customization of a few functions in rsvpmaker-plugabble.php

rsvpmaker_profile_lookup (have it pull in the username also)
rsvp_report – to list usernames in your report
ajax_guest_lookup – if you want to customize the public display of a guest list

In addition to changing the profile lookup, you would want to modify the RSVPMaker form to include a field for username.

I haven’t gone through this whole process, so I’m speaking theory rather than practice. If you do it, please let me know how it works.
