Needless to say, which is the largest social media website on internet? Everyone using Internet on any size of device has the perfect answer; the Facebook. Very recently Facebook has modified its messaging application and do away with Inbox and Other Folder. Now messages from your friends will appear in your Message Box under Recent Tab, while messages from non friends will appear under Message Requests Tab.
In Facebook, the way people used to put comments below posts of unknown contacts now changed completely. Now you can directly type, please see message requests instead please see other folder.
