All I can say is, “WOW!”. I emailed Flickr support because I messed up by associating the wrong Yahoo! account with my Flickr account:

Hello,

I need a big favor. I messed up and associated the wrong Yahoo! email with my Flickr account. “xyz@yahoo.com” mistakenly got attached to my flickr account. The address I want attached to flickr is “abc@yahoo.com”

I tried to fix it myself, but I only got an error telling me that the account was already associated with another Yahoo! ID.

Thank you kindly,
Blake

Within 5 minutes on a Saturday night they emailed me back:

Helo Blake,

I’ve gone ahead and unmerged your Flickr account from your
Yahoo ID.

Regards,

Terrence, you ROCK!!! Thanks. I only have a FREE account, and yet I got incredible customer service. I am already a fan of Flickr’s cutting edge photo features and now I am sold on their outstanding support.
