Oh please. "Publishing" has nothing to do with whether or not a theory is scientific. You're grasping at straws again.
A point could be made that every meaningful scientific discovery (i.e one that has one a Nobel Prize) has been published. The discovery of evidence leading to an intelligent designer certainly qualifies in this manner. Why wouldn't you publish?
But it does put the "theory" out for others to test and pick at, which is the essence of science. If ID cannot stand up to scrutiny, it need not be considered scientific.
