I have set my blog http://esarsea.wordpress.com to share new posts to Twitter, and it works just fine when I publish a new post as administrator. However, I have 2 contributing Editors and when they publish a new post it is not shared. Evidently it's not the blog that is linked to Twitter, but the administrator? Is there a way to fix this so that all new posts on the blog are shared to Twitter?
The blog I need help with is esarsea.wordpress.com.
