And I just heard back from them, and so did the two other people I invited along. So it looks like there will be at least five of us for 10 a.m. on Thursday (please feel free to invite others if you think of them!). The other couple are staying at the Sokos Hotel Torni, which is a couple blocks from the synagogue (I think? someone tell me if my understanding of Helsinki geography is wrong, heh), so I figured we'd meet in the hotel lobby around 9:30ish and head over from there? Does that work for you?

My e-mail is ambyrglow@gmail.com, by the way, if you want to take this off DW.
