Been hearing a lot about folks not being able to invite their FB friends so rather than go over it over and over I started this here thread. Some can, some can't so it is not clear if there is an actual bug involved and if so whose bug is it Glitch or FB.
Some pointers:
!) Go here and verify that you are all linked up like you are supposed to be still.
2) Verify that the friend you want to invite is a friend on the same FB account that you have linked to Glitch.
3) Have your friend go here and verify that they are all linked up like they are supposed to be.
4) After all of that is done, go to the Add Friends link located on the right hand side of the home page, under auctions and hit the Facebook button if it is there or necessary and see if they show up.
I just added a friend via this method and it is working fine for me. If you have any questions on how to perform the above steps please feel free to ask.
Let the inviting begin.
