This was developed for Mediatronica, the full scope of the project still under wraps.

Group Subscription - Utilizing the TextMarks API, I developed a system for users to subscribe to particular group under the umbrella of a single keyword. Once subscribed, users can broadcast messages within the group as well as receive scheduled messages from the group administrator.

SMS Scheduling - The site allows the group administrator to schedule messages through a drag and drop interface (similar to plurk.com) to be sent via SMS (through TextMarks API) to subscribers.
