Ed,
You did not "write" to Jerry" - you "emailed" Jerry. "Writing" requires a postcard, a pen and a stamp....
As well - when "John" and "John" have an exchange - what can one say? Only - that one John is not the other John who wasn't the John that e-mailed John, so John could help John with John's login issue?
I'm pretty sure I'm right - as John is right. Either that John or this John - which makes both John's right. If that's wrong, you should e-mail John. Not the John you think you should e-mail, but rather the other John, who is reading this thread...
HTH,
John
