UPDATE: Ah. *That* was the problem! Lars had written back, but his answer was unhelpful. He had written, verbatim: "If you can read via Gmane, you can post via Gmane." This turns out to be false (since I could clearly read but not post to the Gmane pan users group). But, given your helpful suggestion above, I belatedly logged into my rarely-used throwaway email account, and, lo and behold, in that unused email account, were the missing (now expired) authorization requests from Gmane: > Subject: gmane.comp.gnome.apps.pan.user: Authorization required > From: Gmane Autoauthorizer <auth-bignumber at auth.gmane.org> > > You have sent a message to be posted on the > gmane.comp.gnome.apps.pan.user newsgroup. > > Before the message is posted on the newsgroup, you have > to confirm that you exist.

I'm surprised reading the FAQ didn't bring this up, but, Lars said it's not something they put in the FAQ because you're just supposed to know it. I guess I did, at one time, but, I had forgotten the sequence for posting (which requires the throwaway email be actually used at least once per Gmane group). Mea culpa.
