The mailing lists are our primary community FORUM. This is where we organize projects, announce new releases, plan future directions, and give and receive user support.
Searching a list is a great way to get your questions answered without actually signing up for a list. Follow the Read/Search link for a nice interface from Gmane. Or, browse the olde fashioned way at the official Archives link.
To post to a list, you have to be on it. If you want to see how much traffic a list gets, there is a chart on the Gmane page, or just go to the list archive and take a look. You can opt to receive messages in digest form. Groups of about 10 messages are sent in one email, with a table of contents at the top. This reduces inbox clutter, but means you will get the messages with a delay of up to a day. It is OK to post job ads for work involving numpy/scipy and related packages if you put [JOB] in the subject.
For discussion of JUST the core NumPy package (not SciPy).
Our user-support forum, for discussions of how to use SciPy.
For discussions about the development of SciPy, including code, web site, and documentation.
