@lbranen-ahumada -
I do not think it will be possible. Only way I know of to get back deleted information is with undelete. However, the item needs to have been saved first. I saved a discussion and deleted it. it showed up with undelete. I then created a discussion and edited it, did not save it. let it sit for about 5 minutes (hoping for auto save) and then closed the window without saving. That discussion did not show up with undelete. By the way, when I closed the terminal window with the unsaved discussion, I did not get a pop up about unsaved worked.
For using undelete, go to the home page for the course and then type /undelete at the end of the url (after the course number)
Maybe someone else knows how to recover lost unsaved information, but I do not think it is possible
