Archive Size Getting Out of Hand

[Stephen Irwin]

I'm a big fan of MHonArc but recently my ISP has made noises about the
amount of space my MHonArc archive is using. We have a pretty active list
(20-30+ posts a day) and about a years worth of archived information. The
old posts represent a valuable resource to our users that I would hate to
lose. Anybody faced this problem and have any ideas?

Thanks, as always.
