1) does Listserv care about case-sensitivity in the filter lines (i.e.: User that subscribes is: [log in to unmask], filter line reads: [log in to unmask])? 2) If a user on the filter list tries to subscribe, he/she gets a message line back, etc. Is their a way to notify the listowner when a failed subscription request is received? 3) If you've got a user you want to block from Netcom, do you block both [log in to unmask] AND [log in to unmask] ("ix" is the netcruiser software, I believe?) Are their any other sites that have similar situations? Thanks for all your help...hope I haven't taxed too many brains on a monday morning (assuming that is when you read this...)
