Hi Allen, yes, my point was that there are many reasons why a user (e.g. 
me) will be able to convince themselves why the absence of the seal 
should not be overly alarming.

Specific to the multi-machine issue, I logged into Yahoo twice today, 
once from a machine where I had set the seal, and once from another. 
Seeing the seal only 50% of the time makes for poor conditioning to 
expect it (I do acknowledge that you do guide users on this issue).

If I wanted to phish a Yahoo user, I'd show a seal with a generic 
'Second PC' or 'Home Laptop' text seal, that's the type of message that 
many (this one at least) users would be able to 'remember' creating :-)

regards

paul
