Remember when Facebook launched its new “groups” function and everyone panicked because suddenly people could be added to groups the same way they could be tagged in photos — by other people, without prior permission. Yeah, it kinda sucked.
Stranger still, the old groups still continued to exist, even though they’d long been eclipsed in usefulness by Facebook pages. In fact, I’ll bet you still have a bunch of groups linked to your profile that you’d forgotten about. I’d suggest you go dump them now. I happened to go visit one of the goofy groups I’d joined long ago (Everytime someone plays Nickelback, God kills a llama) and saw this note along the top:
If a group is archived, membership will close and not migrate. The problem comes if a group owner chooses to migrate the group as that pulls over most of the info and all the members. If you’re one of those migrated members, depending on your settings, you may end up getting unwanted messages — especially from groups you had forgotten or thought died off months back.
Here’s the full details about migration from the FB Help Center.
Of course, if you decide to stay, it’s not all bad. If you are part of a migrated group, you can edit your settings (above the group’s title bar), allowing you to select the type and frequency of notifications (or you can turn off ALL group notifications in your account settings), set whether or not it is shown in your navigation sidebar on the left, and decide if you want to allow group chat.
