Hi Gavo.
Sorry I forgot I hadn't replied to this.
a) At this stage, there is no general login to the events calendar. The events are added by a few volunteers (when I nag them enough

).
b) At this stage, there is no email notification of events - though it's a feature I plan on adding (along with some other features) when time permits.
If you or anyone else would like to help out with adding events to the calendar, please let me know.
