Sorry Albright52. Identical results as Terra. I even went so far as to edit the hostinfo.dat and RC file for the news server (geek speak, just nod and smile if you don't understand that

), manually adding the Athletics group. I had hoped that if I got it to show up in Netscape 7, I could get it to prompt me for a username and password. Well, I got it to show up, but all it would do is say something along the lines of "This group does not seem to exist, would you like to unsubscribe from it?".
It is just the way Netscape 7 currently deals with usernames and passwords for Newsgroups, unfortunately. It is about the weakest link in the suite. Not to say that it is inherently bad, just lacking in some functionality (which I guess in your case means bad...).
Tragically, I don't think setting it up in 4.7x and migrating it over to a new NS 7 profile would help simply because 4.7x did not store news server passwords anywhere. You had to enter them each session. It galls me to say it, but you are probably better off using OE, or Forte Agent, Xnews, etc. for now to access this newsgroup. (My recommendation...Xnews).
