I presently deploy "The Events Calendar" plug-in in WordPress. It is great because it stores "Organizers" in a database and provides pull-down access when I am adding events -- similar to how Time.ly stores "Venues" in a database accessible via a pull-down. It would be great if Time.ly stored "Organizers" in a database like you allow users to store "Venues". This would save a ton of time and cut back on input errors.
This is now available for the web application. Please try it at time.ly/timely-free/
