It's funny, but email just wants to be a part of my life. Due to the push notification on my phone, it's almost a feed to me.
I mentioned this in the comments on AVC some time ago: I'd like to see an email service where I can modify the submittal (ex: for NAME@email, I could submit NAME-X-@email.com) where the X automatically created a sub-inbox X when replies to it came in.
