@Inna:

I' think both is useful, because most of our contributors are members in multiple groups, and good to have them both view. But because of this, I prefer the [3] option, because the list view  can be cleaner if it's results an somehow more separated list, eg. headlines as separators, and then group listing based on specific category/headline, and put them to one single page. As this will result an long list, I propose also an jump-to-section clickable links or parts on the page (including back to top), and on the top, and on the bottom add export links as to ical, maybe cron file if possible. I prefer this format also, because when you check these listing on mobile, its more usable, and easier to handle then the other one, I think.

Btw - I'd like to propose also to import the ambassador schedule either into this calendar, then we ambassadors can have one single point to access important dates. Otherwise, can we have this calendar on calendar.fpo later on?
