Joe, Ireland follows Greenwich time, but in France etc. it is an hour different and if they have "summer time" ("daylight savings time" in US). There was talk of the E.U. doing away with seasonal time changes for member states in future.
re themes, I suggested having occasional theme nights,not weekly and that the theme would not be obligatory. I did enjoy the themed sessions at the virtual Getaway. There the theme was pretty much obligatory but in some cases very widely interpreted.
