how to mute conversation in facebook???

If you’ve ever been roped into a group conversation on Facebook, you’ll appreciate this one. By default, Facebook will send you notifications on your phone and Facebook page whenever a new response is posted.

Particularly if you’re being messaged as part of a large group, the notifications can get pretty annoying.
An easy way to ‘opt out’ of ongoing conversations is to simply ‘mute’ them. This will continue to allow you access to the conversation, however you won’t receive notifications of new comments.
Follow These Steps:

1. Go into the offending message, and click on the Actions tab at the top right corner of the screen as you see if below pic.
2. Click on Mute Conversation, and all notifications will cease.

If you’re part of a group conversation, you can also choose to leave the conversation, however this would mean you lose access to future replies. By muting the conversation, you can continue to read new replies at your leisure.

ENJOY...:)
