I meant was there an example post that you could point us to. Perhaps the post did make it out of your area, but just isn't visible to you.
Long shot, I know.
I haven't done anything on Usenet in ages. Most of my interactions that were there are now on mailing lists, and those seem to be mirrored in Google's Groups Ok.
E.g. http://groups.google...ython-users?pli=1
You're probably either going to have to go with a dedicated Usenet provider as was suggested above, or maybe try a mailing list. ISPs seem to do as little as possible to provide decent Usenet access any more.
HTH a little. Good luck!
Cheers,
Scott.
