Caferati's local Googlegroups
A Googlegroup, for those who don't know, operates like a message board. As a member, you can choose to receive all mails to the group, a daily digest, or simply log on at the site and read messages online. And when you want to mail everyone in the group, all you need to do is mail the group's e-ddress rather than each member's e-ddress.
Here they are, City Name followed by the URL to go to if you want to subscribe.

Do let me know via email, or in the comments section of this post, if you'd like a group set up for a city that we haven't covered yet.
