Sometimes I want to comment on another blog and I'm required to select a profile by the blog. I want to comment using my WordPress profile & need to provide my WordPress username to complete the URL: http://<username>.wordpress.com. Simple enough, right? Except that the username I provide doesn't work - I instead get a message that says I need to login to wordpress. I have a feeling I don't know my username. My Website on WordPress was set up for me by a 3rd party developer.
How do I discover my username for this purpose - or is there something else I might be doing wrong when I try to use my WordPress profile to comment on someone else's blog?
