You've been so great w/ your answers, I thought I throw another one
in here. It's been buggin' me for a bit...

I love the option to make a column default to a calculated value. I
use [today] and [me] whenever I can (yes, I play WAY too much!). I'm
curious to know what else I can use. Is there anything else like
[today] and [me] I can try out?

Also, when I use [me] it shows my username. That's okay, but I'd
much prefer to see my display name. When I use a lookup column and
choose "user info" it lets me choose to use the display name. That's
what I want from [me]. Is this possible?

I even tried guessing...[MyDisplayName] was one of many guesses that
tragically failed.
