Interestingly, I had to do a couple of sign-on consolidations this week.
- Merged a Blogger account into a Google account
- Merged a Flickr account into a Yahoo account
Turns out I had a forgotten, fairly unused Flickr account already associated with my primary Yahoo id, and you could only associate one Flickr account with each Yahoo id.
Fortunately, it was fairly easy to delete the forgotten Flickr account from Flickr. Once that was done, it was a straightforward exercise to associate my pro Flickr account to my primary Yahoo id.
