Not sure what you need to do unless you
do not want your Flickr images to go to SmugMug. I haven't even checked to see if I even have anything at Flickr... I don't have any password data in 1Password, anyway.
I do have a "Welcome to Flickr" email from Jan 2013. It appears I used a "Yahoo! ID" to sign up!
They say there is some "unusual activity" in my account. If they were connected to Yahoo! I can certainly understand that!
I didn't think to look in my SPAM folder, which holds just about anything from Yahoo!! (Do I have to use two exclamation points when exclaiming about Yahoo!?
) I found emails they had sent when complaining about "unusual activity" in my account. They included a secret code that was required to enter before I could access my seven images and delete them. Deleting/canceling the Yahoo! account was a bit more difficult, of course. First you have to search the forums to find the hidden link...
