Max Kelly has pointed out that individuals who receive the categories mailing list through a local distribution may not have had their personal e-mail addresses entered on the list of e-mail addresses maintained by Vaughan Pratt and available by ftp. If your personal address did not appear on the lists distributed last month and you wish it included in future distributions, please send your personal address to Vaughan Pratt, <pratt@cs.stanford.edu>, with a copy to me, <rrosebrugh@mta.bitnet>. Thanks, Bob Rosebrugh
