Just use a cube, its easy enough to see from a distance. Place it where you want to be and record the XYZ coordinates from the POS tab. Delete the cube or you`ll be stuck inside it. If its a skyscraper or similar place it so its partly inside the building and raise it on the Y axis of the POS Tab until its clear of the building roof.
At this point you know for sure its directly above that building and the coordinates should work. Stand in the direction you wish to be facing when on the building or at the area, press F2 and record the current YAW whilst in that position. You now have the required XYZ and YAW. Got to go, got another call from Star Trek asking for teleport advice....

Beam me up Scotty.

*** Forget the Festive Cheer in UV. December 2012 I dressed as a Christmas Tree as UV hadn't supplied any festive decoration in the RLC Street. I was cheered for doing it from the members. WO on the other hand gave me an ultimatum, continue doing it and face a permanent site ban. Others wind people up for weeks and months on end, cause trouble and fight yet get little or nothing done by UV. Me getting festive after 4 years here, instant permo ban warning ***
