Suggestion: In addition 2.4 suggestions, explain in the interface what the invitation list is (a list of editors).

3.2. Many organizers reported that this message will cause them to be anxious because it is not clear when the invitation list will be ready. “How long will this take? Where and how will I be notified? How do I come back if i leave this page? Do I need to refresh the page”. P1
