Is there an easy way to check when the last time a list was used (i.e. a
message was sent to the list) under 1.8d?
I'm in the process of moving over to 1.8e, on new hardware.  Before I
migrate lists over to the new box, I'd like to reduce the number of
lists I need to migrate by culling deadwood..

Any thoughts on how to accomplish this?

Cheers
Sean
