True, thanks for reminding us of that, Loxuru. I don't think we have any active members from Northern Ireland, but it's close to where I am, what happens there does have implications for my region, and I've a great liking for the province and its people, of both/all communities. Brexit, whatever the pros and cons for Britain, is certainly a very serious rupture, however the (no hard?) border emerges, and the breakdown of trust between the power-sharing parties (and frankly the sheer clumsiness, incompetence and lack of political skill on both sides) has set things back, the old bunker mentality has returned, trouble-makers on both sides are stirring things ... but 22 years of peace and reasonable prosperity, and a generation that has grown up in that atmosphere, have made a great difference, only tiny minorities seriously contemplate going back to the old days of conflict.
As for fixing the date of Easter, the 19 versus 84 year cycles, the Quartodecimans, embolisms, Dionysius Exiguus, the Synod of Whitby ... don't get me started!
