Feedback on options selected by participants in multi-choice questions, has been made available to subscribers in April 2013.
When editing a multi-choice question in an activity, the facilitator can create text feedback on each each option. This will be displayed to participants selecting that option. In the case of multiple selection questions, participants will receiver a prompt after submitting their selection, listing the feedback for their selected choices.
Currently feedback is in simple text and does not yet support hyperlinking.
