Long ago ding.net (and prior to that shorty.com) offered mailing list services. This is an archive of some of those lists, as well as other lists of interest. Archives of private lists are not available.
I no longer offer mailing list services, there are tons of free options out there if you're looking for someone to host your list.
These are archives of lists from ding.net/shorty.com. Not all archives are complete, I have tried to point out the gaps..
