The SPOTTERON community package is all about communication. With the direct message feature, Citizen Science projects can stay in touch with their user base. From the administration interface, short messages with max. 280 letters can be composed and with just a click sent to all the smartphones that have your Citizen Science apps installed. The phones will then make a sound and your message is displayed in the notification area on the phone. In the Citizen Science app, all direct messages are visible in the user's newsfeed and also in the messages panel, accessible through the main menue.
