I tried to log in to the chat previously, but never could. It's probably due to my current setup, which isn't going to change or anything, so I'll never be able to see any memo that's for me (I think you told me there's one for me, previously).

I don't think it matters. Anyone writing to me from that long ago is either passed away already, or someone I no longer care to have contact with. So feel free to delete it if deleting will help clean things up on your side.
