We need Him now. Where'd He Go? How long.............. is the wait?

The Jews are waiting for him, the Muslims are waiting for him, the Christians are waiting for him. But he is nowhere to be found. Everyone seems to have their opinion on when he will come. Some say he has already come. How do we know when, where and how? Please post your thoughts about the coming of the long awaited Messiah, The Mahdi, The Reformer, The savior of mankind.
