Yes, end users can submit more than one proposal for your event.
Once the first submission has been completed, the end user will need to navigate back to your submission form link to complete a new submission. If included by Admins, the session submitter will have a link in their success page message to submit another submission form.
Additionally, completing more than one submission will result in duplicate contacts being created if the speakers for each submission are the same.
Our recommendation is for the event admins to complete an audit once the submission form closes to remove duplicates and ensure all submissions have speakers assigned to them.
Admins may limit the number of submissions tied to a submission form.
Admins can toggle on Set Submission Limit in the Form Settings to control how many submissions may be tied to one submitter.
