[Matplotlib-users] are gmane posts making it to the list?

[Dan C. <jd...@uw...>]

I didn't get a response to the post below from 20 Dec 2007, and also
didn't get a response to posts I made earlier in 2007, so I thought
I'd check whether posts made via gmane make it to the list.

On a probably unrelated note, I checked the list archives at

  http://sourceforge.net/mailarchive/forum.php?forum_name=matplotlib-users

and don't see any messages after 17 Dec.
