I was poking through the signup file on my listserv facility and realized that a considerable number of userids with entries in that file from the local host here no longer exist. I am sure the situation is true of other entries from other sites. This file is huge and the listserv here is running out of disk space which is at a premium here. Is that a run on sentence or what? Anyway, I was wondering if is okay for me to delete this file, or at least all of the userid's that I am not familar with. I hesitate to do this until finding out exactly what this file is used for since I do not know for sure. I think it is for holding all of the names and userids for people who are registered users at this listserv host. Is that assumption correct?
