If you're looking to implement what then.ly have decided is how your calendar is going to work, then great. Use it. Enjoy.
Just don't try doing anything else with it. Like trying to get it to feed out certain lists of events. Or classes of events. Would be better if their desk.com support worked but nope, that doesn't work either. I asked for a function reference so I could use the plugin with templates... deafening silence... their code blocks short code instances and prevents itself from working. Digging around the source-code, they're trying to implement some kind of MVC in there... a working, customisable calendar would be nice...
I can change the template files but not find out what particular template files the system is looking for.
