Go to the link in the message. (The special:preferences one) Close to the top of the page are tabs that say My Info, Email, Editing, Under the Hood, and Facebook connect (you may need to scroll up to see these). Clink "Editing". Once there, under Editing Experience there is a drop-down menu labeled Preferred Editor. Click the down arrow and select "Source Editor". Scroll down and click "save".
