Mailing List
OpenID has a mailing list for discussion of anything relating to the development and general workings of the system. The list is called "yadis" for historical reasons and is hosted at lists.danga.com.
The mailing list is also archived on Gmane as gmane.comp.web.openid.general, providing the following:
- A web-based interface to the list archive
- A weblog-like page where you can view the latest messages
- NNTP-based access so that you may read the list from your newsreader.
- Various RSS feeds:
LiveJournal users can also add the mailing list to their "Friends" pages. The account used is openid_maillist.
