Each group must submit a one-paragraph summary that includes the following:
A description of the application domain of your choice. State as clearly as possible what you want to do.
A description of the functionalities that you plan to offer. Try to do at least one creative functionality (which doesn't exist in the model site), state what that one is, and explain why you think it is cool to have that feature.
For your reference, here is an example summary for the movie domain.
Submit it in the same way that you submit your homeworks.
