Facebook – Remove Developer Insights from Facebook

There are some new options.

How do I edit my notifications for my groups?

To change the notification settings for a Group you’re a member of, go to the Group and click the "Edit Notifications" button on the top right corner of the page.

Here is the current setup I have used.

On top of this on each post you make a comment on, you must click Unsubscribe so that you are not notified about it on Facebook every second.

This solved it for me. These are for new groups. I checked one of my old groups and it has not undergone this change. Any other tips feel free to comment.

For future reference

I managed to add a custom tab by using this Facebook app. I was a bit confused because at first it asked me to use Facebook as me, so I though this surely isn't for a Facebook Page, but afterwards it asked me which Page I would like to add it to. So I selected my desired Facebook Page and that was it.

I'm a bit disappointed that nobody bothered to answer my question since it seems that this application is quite heavily used in Facebook community.
