Electronic mail, not physical mail.
We have some mailing lists which can be subscribed at http://www.psyc.eu/email but it feels awkward to step down to such an ancient technology, so we do not really post a lot there. Still, it's a push technology, so if you want to stay in touch, get your address into there.
Discussion on E-Mail itself
Implementing mailing lists in psyced
The current SMTP implementation in psyced allows email to be delivered to places using the *place@domain syntax (mailcast). In order to implement mailing lists, psyced needs a way to send outgoing e-mail and either mailto: addresses as persistent place members or nickless person entities identified by e-mail. The other issue with this is multiline messages. How do we avoid outputting them to simple chat interfaces, how do we make them available to multiline-capable clients.. POP, IMAP, NNTP, native PSYC?
