Communication at Mahout happens primarily online via mailing lists. We have a user as well as a dev list for discussion. In addition there is a commit list so we are able to monitor what happens on the wiki and in svn.

Mailing lists

Mahout User List

This list is for users of Mahout to ask questions, share knowledge, and discuss issues. Do send mail to this list with usage and configuration questions and problems. Also, please send questions to this list to verify your problem before filing issues in JIRA.

Mahout Developer List

This is the list where participating developers of the Mahout project meet and discuss issues concerning Mahout internals, code changes/additions, etc. Do not send mail to this list with usage questions or configuration questions and problems.

Discussion list:

Commit notifications:


Mahout’s IRC channel is #mahout. It is a logged channel. Please keep in mind that it is for discussion purposes only and that (pseudo)decisions should be brought back to the dev@ mailing list or JIRA and other people who are not on IRC should be given time to respond before any work is committed.
