I don't usually do reviews.
Wow, this is the best plugin I came across in a really long time.
Normally, I would remove a star because of the lack of sending email notifications in the free version.
However, because this is one of the best plugins I reviewed, I will probably consider buying it for both a thank you and the email notif.
PS. Just try using it with wp-fullcalendar plugin. Wow again.
