Events app - simple events

Hi,

I'm trying to use the Events app to allow my client to enter a title, date and website for each event. All their events are actually conference dates so they do not need or want descriptions, categories or even times. Ideally, I would have a date range for multi-day conferences.

I am having a lot of trouble getting rid of these superfluous fields in the Perch admin UI and more importantly, changing the way dates are entered. I have copied the event.html template into perch/templates/events as the documentation suggests, and have tinkered with it from there. Removing the descriptions and categories template tags seem to have little effect, nor does changing the format attribute for eventDateTime. (I presume this takes a PHP date format character, but the documentation seems to be incomplete)

Anyone have any idea how to truly customise these fields?

Thanks in advance
