[login to view URL] ajax one to one chat(something similar to facebook chat or hangout ) that allow to chat using current database mean that only friends/following user able to chat. It should able to perform emotion input in folder/package which allow me to add multiple emotion. It should base on web socket ,angularjs or others technology that able to perform faster. This live chat should be allow to do multiple chating what facebook or google hangout did. Modern interface and online/offline status is a must requirement for this project . 2. Improve current notification system. Current system already build with notification but not efficient ( need to refresh to see notification) that allow to have a AJAX( realtime). Actually what I need is integrate social network things into my current script.
