Connect to Yahoo Briefcase

Hi Guys,
I need your help to use SmartFTP to connect to my Yahoo Briefcase Storage. It is really possible to use the Briefcase storage to upload my website? Can other people easily enter my website? Can you PLEASE give instruction so I can follow you?

You can use as example only; (Website) for Yahoo Briefcase Storage website, (username) and (Password) to indicate my actual words.

By the way; the actual Yahoo Briefcase Storage URL is http://briefcase.yahoo.com/username@sbcglobal.net or
http://f2.pg.briefcase.yahoo.com/userna ... global.net (no 3 www).

I don't know why Yahoo make a little change in the address after I click and enter it. Thanks In Advance!

Sincerely,
Rino
