Excellent support and does exactly what I need!

I was looking for a simple plugin to have members of my site RSVP for the events we host. Although the pro plugin pretty complex is and suitable for many purposes, support helped me perfectly with enabling and tuning it for our site. Even when I had a problem importing the users, they helped me cleaning the CSV file so it could be imported. The only thing missing is adding all WordPress users automatically to the global invitee list when a certain role is present. Nevertheless, keep up the good work!
