This is much appreciated....:-)
I should like to note that in the case of the comp.sys.amiga.* news groups, that these were first established Jan 8, 1991. The first posts in the mbox archive for comp.sys.amiga.programmer, however, are from May 31, 1994. It looks like the first three years might be missing, at least for this group. I haven't yet checked the other amiga groups yet.
