Hi funsters -- I've been enjoying Google+, and it looks like it is becoming easier to invite people to join it. (It's only been around for a week and they are rate-limiting new people getting on, but that seems to be opening up a bit.) If you'd like an invitation, let me know. (Please reply to me directly, though; I'm sure all of math-fun doesn't want to see it.) --Michael michael.kleber@gmail.com -- Forewarned is worth an octopus in the bush.
