I am looking for a web-calendar that Event Coordinators can log in to and list the details of their events. The events will fall into certain categories, and when that category is selected by one of the participants, it will populate a personalized web calendar. Each category selected will have it's own color and can be turned on and off on the sidebar. Within the Event Details, I would like to be able to send out notifications, text, and emails. I would like to be able to sync with the calendars on any mobile phone, even non-sophisticated ones, and I would like for the participants to pay an annual subscription.
