new email address

[cos]

davis_square@aaaaa.org has been changed, because it got on some spam lists. The new address just has a dash where the old one had an underscore. Help us avoid getting on more spam lists - please do not:
- post the new form of the address unmodified in a public post or web page
- include the new form of the address in a message to a public email list
- CC any email to this address and to a public email list in the same message

Thanks!
