How do I make Full HTML the default text format for the administrator? Currently it is Filtered HTML.
If I remember it correctly, the order that the text formats appear (depending on the permissions you as a user have on using the text formats) is set on the example.com/admin/config/content/formats page. Just use the cross icon on the left to drag an re-order the various formats. Put the Full HTML on the top to make it the first choice.
