>In a world of procrastinators, there's seldom a need for "prepone".<

Ruby raises hand in silent admission.........

Reminds me of a postcard I have hanging on my wall at work:

Don't Rush Me,
I'm Waiting For The Last Minute

Now, with the confession out of the way, I can state that were I one of *those* kind of people who are wont to prepone anything, I would definitely use 'prepone' to assert that such an activity was actually taking place in my life. I like words that become an absolute opposite, just by changing the prefix.
