I have two Yahoo accounts. I need to sign into the one where my Groups are housed, but the password reset goes to the one used for email.?

More details: I have two accounts/profiles because of the Yahoo/Rogers merger 11 (or was it 12?) years ago. At the time I was using my Yahoo account mostly for Yahoo Groups (and I'm on a LOT of them). I had a Rogers account for email. Suddenly my email account was also Yahoo and I couldn't sign into both of them at the same time. I didn't know how to transport my entire Yahoo identity into the new "Rogers Yahoo" identity without loosing anything, so I didn't. For the longest time I could simply open two different browsers (IE and Netscape, or Firefox and Chrome) on my desktop and sign into each Yahoo in a different browser and still have co-current access to both. Then my desktop stopped allowing me to do that. If I signed into one Yahoo profile in one browser, it would automatically sign me to the same Yahoo on whatever browser I opened second. Annoying.

Fast forward to this week. Someone has posted items to the files sections of two of my Yahoo Groups. I tried to sign in to access them, but evidently had forgotten my password. I tried running through my "usual" list of passwords, but Yahoo locked me out before I got to the end. Wait 12 hours. Sigh. This morning I tried asking for a password reset on the original Yahoo profile, but it got sent to my Rogers Yahoo email (which is the email address I had provided). Unfortunately, when I click on the link, it opens a new Yahoo window with my Rogers Yahoo profile at the top and offers to let me change the password. But I don't want to change the password for that account! I want to change the password for the other one.

HELP!!!
