Problem on registering from the backend

Hi there,
congratulations for this plugin. I really like it, but I found a few issues related to manually add registrations from the backend. If I go to “Change Registration” and I click “Register new booking” with an event created with the option “Require WP membership for registration” enabled, the registration form is pre-filled with my data with the fields disabled, but when I try to save it I get the following error “Please fill out your name”, even if the name is compiled. I believe this is depending on the fact that the inputs tags are set to be disabled instead of readonly (see details), and it’s possible that it’s a browser-dependant behavior (I am using Chrome).

By the way, when I create a new registration as an admin, I would like to be able to select an existing user, instead of having the form precompiled with my data.

There’s also an additional issue: when saving the registration with WP_DEBUG enabled the following notices are reported:

Notice: Undefined index: bookerName in /home/.../public_html/wp-content/plugins/events-made-easy/eme_rsvp.php on line 893

Notice: Undefined index: bookerEmail in /home/.../public_html/wp-content/plugins/events-made-easy/eme_rsvp.php on line 894
