I just googled it for a web-based viewer. Worked pretty well, but then I remembered I still have Unseen Masters to play through with my CoC group before anything else was to be inspected. I have too completely forgotten how to operate a stand-alone usegroup viewing application.
OK I couldn't really get any of the google results to work except for one, and that just showed the like ten most recent entries and nothing else. blargh!
http://alt.binaries.nl/viewgroup/?group=alt.binaries.e-book.rpg <- doesn't this work for you guys? There's a search option on the top. Not sure if it archives very deep, but some things can be salvaged. Can't find the initial web viewer I used the first time. Anyway, it's probably the safest bet for some to get a dedicated newsreader utility.
