List and Forum
The mailing lists have been consolidated into one Google Group for users and developers asking questions about XStream's usage, making enhancements requests or proposing improvements for its implementation. Another read-only Google Group is for all kind of notifications like announcements, commit or build server status messages.
Google Groups provide standard mailing list functionality as well as a user interface in form of a web-based forum.
Gmane offers a news server interface for ordinary mailing lists. The service collects all mails from the mailing list and offers them in a news group. The same news group was already used for the old user's mailing list of Codehaus.
The former mailing lists hosted at Codehaus are gone, but still available in public archives at MarkMail.
