Hello,
Though the requirements aren't well specified so I am assuming that this platform will be aimed to provide a system where members will have their dynamic profile where they will be able to upload pictures, videos, music and upload photo albums. Members will be able to search for other members & add them as their friends and can have private messages and chat with them. Members will be able to see the members who had visited their profiles recently. Members will be able to like, and comment on the status/images/videos of other members. In addition, members will be able to post statuses, photos, and videos and can share them with other friends on the website. Users can create groups & events. Whereas the system admin will be able to manage all aspects of the website like members groups, files, images, videos, polls, banners, content, etc.
Let me know if I missed anything or if anything needs to change in my understanding.
Looking forward to hearing more about the newly added functionalities on Facebook like audio-video chat, a business directory with seller store, etc,
Regards,
Rajiv
