Ok, I'm all upgraded. Not an easy process, in part, because of the customizations I had made in 2.1.2.
First - THANK YOU - I am so happy to be able to offer unlimited submission types to my conference organizers. Of course, they can't be completely happy. Otherwise, our jobs would be too easy.
So, a feature request: The ability to set different deadlines for different submission types. For example, for one of my conferences, the deadline for symposia will be March 1, the deadline for students wishing to be considered for a graduate student award is April 1 and then the deadline for regular talks and posters is April 15.
