My apologies to anyone who is getting strange things bounced to them. The people who run our listserv had given me a change of subscription address that turned out to be incorrect. To subscribe to TPI, send e-mail to <[log in to unmask]>. Leave everything blank up to the message and send the message "sub <full name> tpi". Sorry for the inconvenience - Dave Reifsnyder Co-Editor, T.P.I.
