It is my impression that the Caffe project has matured to the point where a caffe-users mailing list would benefit the community.

Users of Caffe will naturally have questions about the library's use, bugs they encounter, difficulties with compiling and running the code and demos, etc. As these questions arise, where should users articulate them? There are at least two natural destinations:

(1) Submit the question as a Github Issue

This seems to be the only option currently available. In my estimation, of the 18 most recently submitted issues, 13 are "questions that would typically be asked on a mailing list" and only five are "bug reports and infant PRs". I've annotated these 13 of 18 in the below screenshot with a red "?"

(2) Ask the question on a mailing list

An alternate destination for such questions would be a caffe-users mailing list, explicitly designated the purpose of allowing users to ask such questions. This would allow Github Issues to be reserved for actual bug submissions and discussions of proposed changes.

For pylearn2 I've found pylearn-users and pylearn-dev to be very useful. These lists serve not only as a designated place for users to ask questions, but since the list discussions are available online (via Google groups), then after a while the project ends up with a FAQ that the community writes together, indexed by search engines so that the next person doesn't have to ask the same question.

If (2) sounds like a better approach than (1), then we should make a mailing list. If (1) is deemed to be adequate, then I would suggest at least endorsing this strategy on the Caffe homepage, so that new users know this in an encouraged avenue for inquiry.

Thoughts?
