Free vs Professional Documents
A Displayr document is either a Professional document or a Free document. If you are using the free version of displayr, all of your documents are free documents, and you can't create professional documents. If you have a professional license for Displayr, each document starts as free, and becomes professional whenever you use a professional feature.
How to tell if a document is free or professional
After you log in to Displayr, you will be shown your Documents page. If a document is professional, this will be listed to the right-hand side. If a document is not marked as Professional, then it is a free document.
What is the difference?
If you have a professional license, free documents will not consume your server time and may only be published publicly.
Users without professional licenses may not collaborate on professional documents. People with a professional license may collaborate on any document (so long as they are part of a User Group with the relevant permissions).
