How do you UNBlock someone?

Oh, Sorry I didn't see that part..... If you're not sure how you blocked them it is most likely because they were the ones who blocked you.

Go to the Friends Icon in the tool bar to the left and scroll down to the bottom and you will see in a box 3 categories. The furthest to the right is Blocked. UnBlock them. It won't solve your problem because a block is automatically a 2 way block (No clue why) so you will have to wait until they unblock you from their end which almost never happens. Good Luck!

Not sure how we did it????
