I've been 'cleaning' this old Thread of various email addresses which are not permitted in this Forum and trying to make some sense of the rest. I'm not sure whether mentioning other playgroups is considered a hijack or not, but the group which the original poster wrote about looks still to be in existance and the Wollishofen group too, but I don't think either poster has been on-line here recently.
It is quite an old Thread anyway but if anyone is really interested in these playgroups and gets no reaction to a PM, Google is your friend!
