   So weeding out all the technical stuff that I don't really understand, I   
   think you are saying that I can't have two email ISP's in my SeaMonkey   
   setup. Right now I have Earthlink defined and I have Hotmail defined but   
   with the new authentication going on at Gmail and Sbcglobal only one of   
   them, Earthlink, will work.
