After receiving the achievement "Fallen Gate: Quester", I went into Twitter and Facebook to see what title was actually posted. Unfortunately, there was nothing! However, when I selected "Send an Update" option to manually post a test picture, it worked perfectly fine. So, is EQ2 Share broken or simply disabled on Fallen Gate?
It goes to an account that is strictly game related. Only people interested in the game, such as my old guild mates, have friended that account. Mainly so they can harass me for still playing.
