Im from Mozambique and I want to build a website where studants and teachers can communicate among themselves.

Its a website like facebook for students where they can create a profile, send photos and videos, post blogs, interact with students from other schools, etc.

The teachers can post articles, subjects for studies, make a FAQ of certain subjects, post lessons, home works and interact with teachers from other schools.

The Schools can have a page where you can find information about them, their history, contacts and where they can publish the annual results from the students.

Every student and parent will have a username and password access the information about the annual results.

The design can be made by us, my biggest difficulty its on the programming side.
The website can be in any programming language like ASP, PHP, HTML, etc.
