Using internet explorer, you can also put http://whateverhere () google com

@ sign. I noticed that one day while putting in my email address in for
hotmail. 

And not _just_ in IE.

What you have described is, in fact, more or less the "expected 
behaviour" of a web browser given the input you described and RFC 2396. 
Surely to comment in such a thread you have read the RFC that defines 
the format of URIs:

   ftp://ftp.rfc-editor.org/in-notes/rfc2396.txt

Search for "userinfo".

I'll repeat my earlier suggestion that I'm sure it would be greatly 
appreciated all round if only moderately clueful responses were posted 
in this thread...
