[OT] Eternal September question

I *think* I may have solved my problem with Thunderbird but I still have one key question.

I removed the newsreader account I had (after writing down the settings) and then re-created it. Now, when I try to manage subscriptions, I actually get a list of newsgroups which is a big improvement.

However, the list of newsgroups I'm seeing are those that are specific to Eternal September and NOT Usenet newsgroups.

I've seen and fixed that problem before but it's been a while and I've forgotten what I did. There's one additional step I need to do to see the Usenet newsgroups.

Can anyone remind me what needs to be done?
