What's my Flickr "Name"?

For the purpose of adding a flickr link into my POTN signature, what info should be input into the "Your_Flickr_Name_Here​" highlighted area of the signature builder. I've tried "larryspics1", "Larry Johnson" and the link https://www.flickr.com​/gp/117800205@N05/7T4v​4E are get an error message for all of them when trying to link to flickr.

Try this:

https://www.flickr.com​/photos/117800205@N05/

and if that doesn't work, just use:

117800205@N05

after a zillion tries, entering the entire flickr web address worked.
