Duplicating a Substack

[Stephen Paul McNutt]

The weird thing is I've done these several times already, but now I  
can't figure it out.  I want to duplicate one of my substacks so that  
I can rename and modify it--rather than starting from a blank  
substack.  Seems like that should be easy, but nooooooooo.  Thanks in  
advance for any help you can give.  I did look through the Revolution  
documentation, and the only way I can find to do it is to change the  
mainStack function of some substack in another stack to move it to  
the desired stack, but I know that's not how I did it in the past.
