So you will click on the comment button. Go ahead and put your comment in the box at this time. Then you will see the screen above. It says select profile. If you do not have any of those profiles I would suggest selecting Google Account.
That will take you to this page where you will choose the bottom light blue box. "Don't have a Google Account?" Please click on the get started button.
Now you get to fill in all this fun stuff.
Should take you back to this page where you will still need to hit Post Comment to get it to post.
Comment is now posted. I hope this helps someone.
