Word 'their' is mispelled

The word 'their' is spelled 'thier' when you remove an attendee.

From rsvp.module:

$content .= '<br />'. t('Deleting an attendee will delete thier responses and remove thier access to their invitations to this rsvp.');

changed to:

$content .= '<br />'. t('Deleting an attendee will delete their responses and remove their access to their invitations to this rsvp.');

Attached the updated rsvp.module file.
