I like to use Tin newsreader on terminal communications software on a 
unix machine.  Several months ago, I entered a newsgroup that I had read 
many times before, one with many posts, and it said no articals.  At the 
top of the screen was A0 T0 and K (which I assume means the amount of 
memory/bytes the articals take up in the newsgroup) with some large 
number.  This indicated to me that there were articals there that tin was 
not seeing.  Over the next few months, this phenom happened to several 
other groups.  I have not been able to see any articals in them since.  I 
have even posted to some of them and gotten e-mail so I know the groups 
are active and people can see my posts (though I can't).  As far as I 
know I do not do anything to cause this and it seems to happen randomly.  
Any tin experts out there?  What causes this and how do I fix it?

P.S.  e-mail me a response since this might be one of the newsgroups I 
can't see anymore.  :)
