Well, the teleporter bug in the client is still unfixed (don't we love it all?), how to work around it, was explained by Torley Linden in the knowledge base. Simple: press Ctrl-Alt-V, then you've got the button back again.
But well, not everybody reads the knowledge base or spreads the word around, many are still complaining about this unfixed bug. Some are trying to make money with it, selling their own teleportation tools right now.
How about fixing the bug or spreading the word to render this device unnecessary, again? This would be great, don't you agree?
