Documentation Lists Core
The q-lang-users list is provided for discussing all issues related to using Q. Here you can post all your questions and comments concerning the Q interpreter, the standard library, the add-on modules, etc. There is also a second q-lang-devel list intended for discussing the development of the Q interpreter itself, but it's hardly used right now. As q-lang-users is a fairly low-volume list, you're encouraged to use it for all things Q.
For those who wish to keep track of cvs commits we also offer the q-lang-cvs list. This list is most useful for developers and may generate a fairly high volume at times.
NOTE: You really need to be subscribed to the lists to be able to post there, as a measure to fight spam. More detailed information about the mailing lists and a web-based interface to subscribe to the lists can be found by following the links above.
