Thanks so much for the quick response! I apologize for not giving enough information when I first posted this message but the problem is that I did check to see that the e-mail address was correct in the database. It was. So then my next step was to check the instructions in the listserv owners manual. There was nothing about this type of message. That's when I was stumped. Any help would be appreciated and thanks again to everyone who responded. Ganina Lagodsky
