I have now found out how I can post to the blog from my iPad or from my iPhone. This will be great as I can post from anywhere when I have time.
To enable this in the WordPress app I had to go to the blog and login as admin, then go to setting/writing and select all XML-RPC services. Save changes and put in the blogs username and password in the WordPress app.
This blog entry is about adding a global2 blog to the WordPress app and this is my first post as a test.
