Thanks for a great update. I've started working with Drupal recently, and tried using MarsEdit 3 with it today. I'm getting a Get Recent Posts Error: Blog API module is not configured to support the 1 content type, or you don't have permissions to post this type of content.
As I have permissions for this user to blog, it must be something to do with the content type. Any clues from anyone using Drupal? I note there was a mention of this recently in a topic now closed.
