In certain lists hosted here (all with SEND= EDITOR, EDITOR= (list)), we've experienced some hit-&-run posting -- [log in to unmask] will subscribe, post something generally nasty, and immediately signoff. One of our subscribers suggests that all new subscriptions be set NOPOST by default for 30 days to prevent such occurrences and also to allow new readers to serve an apprenticeship, thereby avoiding uninformed or otherwise inappropriate postings due to inexperience. Can anyone suggest a mechanism (beyond DEFAULT-OPTIONS= NOPOST) that can implement such a scheme without the list owner having to keep manual records of subscription dates? What would help with this and a lot of other matters is a user exit to allow local processing of new subscriptions. /bec
