We have found a solution for those of you who haven’t been able to post to the blog! First: make sure you are logged into the blog under your own email (you can tell what email is logged in at the upper right hand corner of the blog.)
Once you are logged in as yourself, click this link: https://www.blogger.com/edit-profile and give yourself a display name. Once you’ve done that, you should be able to add and edit posts.
