Unsend Email
However, earlier this week I realized that if someone were to implement such a system, it would change the way we email. For example, this week while preparing for a trip to London, I kept sending email to my London co-workers with items that I'd need while I was out there (a certain piece of hardware, a screwdriver, etc.). I kept thinking of new things and adding to the list. It would have been neat, if emails were unsend-able, to have just revised the list in-place, until they had read it. At which point I'd start a new list. That way they would have seen 1 well-constructed list instead of receiving dribs and drabs. Since we're at very different time zones I was never sure when they'd last check their email, and I didn't want to risk missing them by delaying until I had the complete list, but I didn't want to annoy them by constantly saying, "Oh, and one more thing!"
Does anyone have friends on the Chandler team? Do they have a better solution to this problem?
Anyway... I just think that if you could "unsend email", we'd find many applications beyond the, "Oops, I didn't meant to send that" original inspiration.
