Re: Deleting emails
Somewhere I have a backed-up export of all my old Compuslurp email. Back when I had to deal with UPC codes I had one particular message that gave me a formula for calculating UPC checkdigits, and multiple times had to go back to my CIS mail for reference like that. Somewhere also have a message there from JMS himself.
But I do occasionally purge out emails (especially after a search for something brings up ancient notifications I dont need). It's also fun to find old technical/customer support exchanges where I was chewing someone or another a new asshole.
