I have a social network website: [login to view URL] I need to add some features like: -Admin dashboard like this: [login to view URL] (UserName: admin Password: admin@123). The site already has a admin page but only shows the registered users and admin can delete them. -Edit the login page /change some icons and texts -Edit the feed page (set a "Hello message" like "Hello $name_of_user"). -Add a flat chatbox like on Facebook (it has message page but i need flat message box to talk with more persons at the same time -Add cover photo (at the moment it has only profile photo -Add photos album (when user uploads photo through a post, goes to the feed and to the album.
