But you used an email address to register with ElReg.
If you hadn't, you wouldn't be able to comment.
Use that email address.
(Shirley you know how to set your email address to whatever, regardless of where you are really sending it from, right? Honestly, I don't get the recalcitrance to using email for a situation that email is eminently suited for. Makes no sense. Unless all y'all are just being bitchy for the sake of being bitchy, of course.)
