doesn't this block bounces?  I seem to recall one time where this was enabled 
by default and was blocking all bounce messages, which is a VERY bad thing.

nano? *ducks*  a lot of new users would get stuck in vi, so I would recommend 
saying nano or pico there, advanced users will recognize this as a text 
editor and use their editor of choice.

I know the first time I got in vi by accident I was like "wtf how do i get out 
of this thing!??" :)
