Facebook has introduced with the new feature of group chat to give users control to share their information and stuff. It has become a lot popular these days. If you have a group of people discussing about something, then this is the awesome solution. But sometimes, some of your friends in a group are online and having a chat but you are not willing to join the conversation on the group chat then, it becomes quite irritating for you as facebook pings you with those red coloured digits signifying the many lines of text sent will glare at you like anything!
So to avoid this, do this :
Go to the edit settings option which is available on the right hand side top as below.
Now Uncheck the “Send me group chat messages” option and Click on Save Settings and You’re done! :D
Enjoy and Have fun :D
