Hi, thanks for your plugin. Have you considered adding a functionality to have multiple dates for the same event? I went through ALL wordpress event plugins and there's NOT a single one that uses custom post types and offers the possibility to add multiple dates. I'm thinking about a button to create unlimited copies of the field group (date/time) like the WPAlchemy function have_fields_and_multi(): http://farinspace.com/wpalchemy-metabox/
Would be unique!
(I'm currently working on a playing schedule for a theatre. Each production plays on several dates.)
