is there anyway I can upload a powerpoint file straight from safari onto the app instead of emailing myself it and having to open it through mail? Right now I would either have to upload the file on my mac on the slideshark site and then it shows up on the app. Or I would have to email myself the file as an attachment and then long press and open it with slideshark. I use blackboard for school so I would like to just open it from the blackboard site on to slideshark. Is there a way of doing that?
