[Mailman-Users] Expiring mailing lists

[Gretchen R Beck]

I noticed that a couple of sites lists include expiration dates for their mailman lists.

I'm interested in using such a feature on my site; is there a particular version where this is available, or is it customized site-by-site?  Any pointers to information on implementation? [Also, if this is the wrong list to ask this question, please point me to the right one]

Thanks!
