Have a convention organizer section
I'd like to see a section, accessible only to convention heads using the official convention Email address, where con heads can detail their experiences with Guests. This would allow us to determine whether or not a particular Guest may suitable, or if we should avoid them for being a drama queen.
Believe it or not, this is actually something which has been on the drawing board for a while. We hope to add it in the next few months since there are a number of other new features for convention organizers which are dependent on this section being done first.
