mysql question

I'm having trouble with my mySQL server on my local computer -- Whenever I type mysql -h localhost -u sano -p and it asks for the password, and I type it in, it returns with: error 1045: Access denied for user: 'sano@localhost' (Using password: YES) My questions: 1. Why does this happen? 2. How can I tell if I ever set a password for this account (I can also access by just using -h and -u without the -p flag) 3. What's the command to change my password? 4. How do I add additional usernames? Thanks in advance! Chris ___________________________ got sano? (new design!) http://www.rit.edu/~cms0670
