I wish Esri would follow Oracle's lead and make its ArcSDE instructor led training manuals available free online in PDF format. Or at least sell the training manuals separate from the courses. It's often a tough sell to get a course approved for a current iteration of software one has already taken. Yet ArcSDE is product you want to stay current on. Is there any movement toward selling the training lecture and exercise manuals separately? The training materials often contain great content not available elsewhere in the Esri doc set.

I created an idea for this. Vote on it if you like:
