Some of my friends wanted a free messenger API for their websites, but doesn't want all the traffic and management to happen on their end. Thus I have created a simple messenger service, 'chat.rankaru' for them, though it is still on it's initial build and still lacks other features. The initial build can perform messaging by user to user exchange or by establishing a group, though it still misses a few features such as storing message in a database or sending secure messages.\r\n
Update 05-17-2016: This feature has been decommissioned. Link is accessible.
