I suspect there were a lot more than 2100 UUCP hosts at its peak. I haven't had much luck doing searches on Google Groups - it often just gives me the first page and refuses to sort by date. Is there a good way to mine all the postings to a particular newsgroup, or all of them in a particular year?     Mary Ann
