This plugin does what it says. This would be awesome if implemented via shortcode instead of a dedicated page. The, what seems to be, setup page provides no indication of what is happening or why... Each user seems to be able to create a calendar ad hoc - which is cool and these created calendars seem to be viewable only by that user - which is exactly what I wanted! The usage of a dedicated page really hampers this plugin. But, it is a very nicely laid out page 🙂 I'm only giving it 3 stars because of no documentation, no explanations, and no shortcode. The dedicated page I'm sure makes it easier for the css and other coding aspects, but makes usage inelegant overall. I hope to see these items addressed very soon! With these concerns addressed - this plugin will be exactly what we want on all our sites! Ken
