I just peeked at my FReepmail account and added up all those I have saved. There are 547 from 74 different FReepers, plus 319 which I sent to myself before the "sent mail" feature was instituted in FReepmail. Most of these could probably go... someday I'll get around to it.... (famous last words of a hoarder/procrastinator).
Some of these will never be deleted, such as the 35 from Angelique. Regrefully, I had deleted a number of them from her before learning of her passing.
I won't mention my Yahoo! account or another account with 100 mg of storage space that is 50% filled. <}:(
