Archiving Former Members, Prospects and Guests

My club's new VPM is asking if there is a way to "clean up" the lists mentioned above w/o deleting. She asked about archiving, and I wondered if there was a way to archive former members, prospects and guests?

No there is no way of archiving. You should actually be thinking of deleting, guest and prospects after a short period of time.
If someone hasn't joined the club after a couple of months why do you hang on to their information?

On average an email address does not last longer than 18 months.

Hi, Brian, I'm honestly not sure. I was assisting one of our club's founders as she was the webmaster, but they never clear out any of the old messages or delete any of the older membership/prospects/guests. For as long as I've been in the club (5 years next month), that's been their unexplained practice. I agree with you, should be deleted, so now it's time to poke the bear. Thank you!
