that's weird, cos i get something similar sometimes when i log in:

Hi, you're one step away...
Yahoo is changing the way you can recover your account in case you forget your password. The following information is required in order to use your Yahoo! account. Learn more
Enter an email address: (where Yahoo! will send password reset and account emails)

this comes up just after i've logged in but i keep clicking the 'remind me later' button, then i go to my emails.............

anyone else had this??????
