If either the {uploadlink} or {uploadlinks} tag is used in the email sent to speakers, then a link to a personalised file upload page will be included in the email. Each speaker gets a unique link that will let them upload and manage files for only the presentations that have been allocated.
As a speaker uploads their presentation files, they are given the option to allow publishing of their slides, or not. If permission is given, then a PDF version of their file will be made available on the publishing page for the event, if the feature if being used.
If changes are made to the programme, and the speaker is added or removed from a presentation, then this will also reflect on their speaker upload page.
