My very long search for such a website solution was dotted with installations, tests and failures of many previous web-based calendars. All were either too heavy, too slow, or offered cumbersome interfaces.
A download and test today of LuxCal Web Based Event Calendar proved this is an obscure but potent rival waiting to rise forward. By my help, that will be the case!
Version 2.7.3 LuxCal Web Based Event Calendar I downloaded was easy to install, easy to configure, and easy to use without a cluttered interface. If I would dare ask anything more from the developers of this open source product, the request would be for 1) internal user or external e-mail list management for mass schedule notifications, 2), Youtube video or sound uploads, which can greatly boost the attendance and response to certain scheduled events.
With nothing more to add here, I wish the LuxCal developers much visibility and prosperity in the new year, even by my help!
