At least once a week, I get an email from someone requesting access to one of my google documents. The link to the google doc. is on one of my blog posts. I think there are pinterest steps being skipped which is causing this problem.
When you want to pin something from a BLOG POST:
1. Click on the title of the post (article on a blog). The title of the post can be found under the date of the post. The arrow points to this post’s title.
