fedup from beta

[Richard M. Vickery]

I hope this isn't in HTML - please alert me if it is; I don't know if 
fedup changed the mail setup, and forget where Thunderbird's check-box 
is to fix it.

I'm just curious as to how to fedup when F19 comes out; I am aware that 
the command is

fedup F18->F19

however, this is the beta as opposed to F18. Of course, F18 is available 
to boot into, and I guess users boot into that to use the command above. 
I suppose I answered my own question.
