The ID is a unique number that is allocated to the symposium when it is submitted.
The other columns show the Title, submitter and the number of abstracts grouped under the symposium.
Click on the symposium title to see the details of the symposium, see example below. You can edit the data on this screen if you need to.
You can change the status of the symposium and mark it as Accepted, Rejected, Pending or WIthdrawn.
