The latest move comes from Facebook after WhatsApp rolled out its PC version of its popular chat service as at January 2015. To get Started simply Visit Messenger.Com and sign in with your Facebook account details. The conversations you made can also be continued on a smartphone through the Facebook Messenger Mobile App, which already has about 600 million users.
Facebook Messenger Users can also send pictures, stickers, and the signature big thumbs up which the Mobile FB Messenger App also possesses.
Below are shots from my conversation while using the Faqcebook Messenger on my Desktop.
