I still think that this is a necessary functionality of a conference CMS. It should be straightforward for presenters to upload their poster, paper or slides after the conference is over (or whenever they have them ready). The whole point of PKP is to make it easier for researchers to share their work. I have had a number of conference organizers ask me for this feature over the years, but instead I have to give them this workaround:
I also noticed that the terminology has changed. On the backend in Setup, 2.1 Submission Process, the box that you check is now labeled as:
Abstract followed by proposal (2 rounds of review required; first for abstract, second for proposal)
where it used to be labeled as:
Abstract followed by presentation
, which to me sounds like the system isn't even considering the uploading of presentations to be an option any longer?
