running vacation

[Paul Migliorelli (+1 3 0 3 5 4 3 2 3 1 1)]

Hi all.  As much as I've read the docs manpage for vacation, I seem to 
have no clue to get it to work.  Could someone maybe send along some 
concise instructions as to how to do it step by step?  I've always gotten 
stuck where it wants you to edit the message or whatever, but I can't 
figure out what editor it throws you in and or what you do if you type 
vacation at the shell.  Also, what tdo you do with it in terms of mailing 
list traffic??  Just curious.  Thanks much.
