Simplest solution: We can allow presenters to upload stuff here. That will give them full add/edit/delete on this page. Should be fine, but not totally secure.
- Create some kind of anonymous upload dropbox somehow and have someone curating the materials here for download. Some technical challenges and some labor involved.
- Create pages here for each session. Give the present edit access to their own page. Some different work required, but probably leads to a nice result. Might be worth doing. Maybe some way to automate this? See an example of this here: Presentations 2
