   I sort of understand - though through a glass darkly, as the saying   
   goes. (But don't try to enlighten me!)

   Most definitely! That's like telling people they can only watch certain   
   TV stations!

   Yes, they're sort of subsidiary email addresses. For example, my old   
   Demon one was @soft255.demon.co.uk; the   
   .demon.co.uk (and I think .demon.nl) obviously belonged to Demon   
   (and eventually Vodafone), and eventually they stopped renewing it.

   I don't think that _could_ even be done.
