FairSpot Post WRITE

PAD: https://pad.hackerspace.gr/p/FairSpot_Post to be based on the info in this pad: http://board.net/p/FCLN.fairspot, but also other things can be added, in order to make it no so much a report of Athens FairSpot itself but as an example of what other nodes can do, adding maybe with other possibilities.
