A 6 year old email.
Who keeps their email for 6 years?
While I don’t save everything, I have several thousand saved messages, some going back to the the mid/late 90s.
I was just revisiting a series of messages I exchanged with Discmakers in 2011, refreshing my memory on a couple of DVD projects I published through them.
Things like that, in-depth discussions with friends, etc., are nice to have around when you need them.
