I've never checked my gMail web mail before.

Signed up bc it was required for something-or-other... probably

Among all the spam, I just found a returned message, subject:
"Pete Cresswell wants to talk to you using Google Talk".

It had bounced from the address "fio…@gmail.com".

The content sent to that person was:

can talk to each other for free over your computers.

I don't know anybody named Fiona and I sure as hell wouldn't send
such BS to them if I did.

Questions: - Who sent this garbage out with my name on it?

          - Why?

          - How many people out there think I'm spamming them?

Seems like Google's the prime candidate considering the
self-serving content of the text.

Or are there other possible explainations?
