I can't seem to find posts before 2006 or so on a cursory search for a random comp.* group on usenetarchives.com so where are these updates posted on either www or nntp? Also, I believe usenetarchives.com deserves an improved web ui on top of just hierarchical navigation by group.subgroup... + month even if the preferred protocol is nntp.
