Barbara, our arrangement was that one of us would suggest a time when we might meet. Usually the same place and if possible a Friday afternoon but not fixed, so in fact whenever convenient. Annie Long and/or I used to suggest when... She moved to Portugal, I tried. I turned up, nobody else did. I did it again, turned up but that coincided with a group of British women meeting, which I thought was 'us' since a couple had usually shown up. Then my daughters' college arrangements meant that since I was in Bergerac I should collect them, but that meant if we had stuck to Friday afternoons I would have had to leave too early really. So I gave up trying to organise, but it is open to anybody else (perhaps you) to put up a word in the Bergerac group.
Personally, I would prefer us to be the kind of mutual help mob rather than having a coffee, you know advising newcomers on whatever questions they raise where somebody knows the answers. In that respect, local groups, like networks, can be very useful.
I live reasonably near to two budget airline airports, La Rochelle and Poitiers. Throughout the year my guests fly in and out of both. We often fit a meal into an airport run but would never consider eating at the airport itself. Why on Earth would we think of doing that when there is so much choice in the two towns?
