I type in a question in the Q&A tab it remains there until I exit my lesson then it is gone. What's up with that?
How do I use this. Right now the only thing I know how to do is post in a Textkit forum.
As Bert says, after asking the question, first publish the lesson and then close the lesson. Do this via the main context menu in left pane. This menu can be raised by right-clicking on a word in the lesson text.
There's no requirement to publish immediately. Just make sure you publish and close when you are all done.
