I can't link up my flickr account!
There are a couple of possible reasons why your flickr account is possibly not being found in the account searcher:
Your screen name is different from your username. Flickr uses your screenname, not your
username to find you in its system. To check your what your current screen name is, go to your
Change My Screen Name page
for your flickr account.
Your privacy settings are correct on your flickr account.
Take a look at your Hiding from search page and make sure that all
boxes are unchecked.
