the summer is pretty dead in terms of group activities but things should be picking up soon. There was a book group that kind of fizzled out because it's so hard to get enough copies of books in English, and a film club that hasn't been extremely active lately because it was sometimes hard to find people who were able/willing to host.
one of the admins of the group (initials AK) is very active in posting and organizing activities, so keep an eye out for that.
I also recommend signing yourself up for the multicultural center mailing list. They occasionally sound out mails with info on multicultural gatherings and activities. Their website is here:
for the bolder, if you sing, now is the time that the local choirs are recruiting again. I'm a member of a nice one near downtown if anyone's interested. We generally always need male voices and altos (sopranos can be negotiated too). PM me if you're interested. The group is mostly Icelanders but we occasionally have people who're around for a year or so, and everyone's welcoming of them too. We're signing Magnificat this fall and practice starts this week.
