Nathan Brindle at LSOFT.COM suggested I bring my problem to you for help. I realise that the answer should lie in the List Owner's Manual, but I've been unable to follow the instructions in Section 8.4 and 8.5 successfully. I am co-owner of the UK-HOME-ED Listserv list on AOL and have been attempting to register and store file archives. My Listserv manager has created a sub-catalog for the list. I now need a detailed example of which commands to send, in which order, including when to wait for responses from Listserv. Specifically, I need to register and store : useful.txt useful.txt private owner in tne UK-HOME-ED.CATALOG It has just been suggested that there may be an error in the way the sub-catalog is set up - how do we know if this is a possibility? Thank you for any help, Joyce Moore.
