I haven't been able to find much documentation on Task Chain. I've used it before for HotPot, but can it be used with other activities? For example, would Task Chain enable a jump from the conclusion of a SCORM directly to the beginning of a Moodle Quiz without user input?
"yes", you can use other types of task with TaskChain (e.g. Textoys, Qedoc, iSpring, Xerte and HTML files), but "no", you could not use TaskChain to deliver a SCORM activity and then go straight to a Quiz activity.
