stupid questions

[Shirley]

Say I wanted to delete a post I had made.  How would I do that?  (I'm 
not planning to; I just don't know how.)

Also, if you reply to someone's email address from a post, rather 
than to the list, does a copy of that email/post get put anywhere?  
For instance, if I decided that I wanted to reply to Cindy or Shaun 
or June off-list, wrote my text and clicked on "send", would I ever 
be able to see what I had written again?
