I can't seem to find a way to change my password.  I must be set up to automatically sign in to my e-mail.  I never use it, but the Yahoo group messages are forwarded to a different e-mail address.  address.  When I started joining Yahoo groups, I assumed I needed a Yahoo e-mail address so I created one. I assume if I removed Yahoo from my computer it would mess up my group e-mails.  Obviously, I know next to nothing about this.  I have enough trouble dealing with a computer that constantly crashes.  I'll change if if I can find the page to do it.  When I click on Yahoo, it goes right to my e-mail.  Now what?  Sue
