Prodigy.com addresses are from the old Prodigy Classic service, which goes out of business October 1st. (Prodigy has said that Classic is not Y2K compliant, and not worth making so, so they are getting rid of it.) Prodigy.net addresses are from the Prodigy Internet service, which will continue. Any list subscribers, query submitters, etc. you have with prodigy.com addresses *should* be sending you new addresses, but you might want to drop them a line and remind them before October. If they don't, be aware that any addresses you have from prodigy.com will stop working at that point.
