From the http://moodle.org site if you go to -> Support -> Forums you get the full list of support forums. The course we are in, "Using Moodle" http://moodle.org/course/view.php?id=5, is the main discussion "Forum" in englsh.
Unfortunately, it is not that easy to find the correct forum from there in those close to 100 links to individual forums. For a general inquiry like this the forum "Moodle design" http://moodle.org/mod/forum/view.php?id=7135 is the right place. You can find more about the structure of "Using moodle" in that forum, especially in the discussion "Ideas needed: moodle.org improvements" http://moodle.org/mod/forum/discuss.php?d=196302.
P.S. I will soon move this post to the "Moodle design" forum (from "Hardware and Performance").
