How to Increase the Number of Allowed Co-Authors for an Abstract Submission

I increased the general setting to allow up to 10 co-authors for abstracts, but authors can still only add up to 5 co-authors. Is there another setting that might be limiting this?

In Dryfta's abstract management system, simply increasing the allowed number of co-authors in the general settings may not be sufficient. 

Each abstract submission type can have individual settings that override the global limit. To allow more co-authors, you should go to Advanced Setup > Submission Types and check if the settings for the specific abstract type you are using have been configured to a certain co-author limit. 

If yes, then increase the co-author limit there as well. This ensures the limit is applied correctly for that submission type.
