I am Looking for a Simple site with good looks and user-friendly environment. I need the following pages on my website
Login System(Login/Register/Member area)
Profile Page for my students
Chatting and Friend Request system(friend request and unfriend)
Wall System like facebook
Who is online system
Settings Page(change password and change profile pic(Webcam or from local files))
If you can then try to make the site a bit optimized as because I don't want my users to wait 20sec to load each page.
Remember the site will be used by students and they will spend about 3-4 hours so make it user-friendly. You can use any CSS framework you like for this project.
