I just performed an update, small nonetheless satisfying, since it fixes the map and makes the "send troops" button actually useful.
Now the map correctly show the tiles' info on the right side; the "Send troops" button, that until now just sent to the Head Quarters, puts in automatically the coordinates for you!
Also, the registration process has been fixed some days ago, thanks to karlos666uk, that reported the problems - I knew already that it was faulty but somehow, clumsily, I just assumed users would figure out what was wrong with the link and manage to register anyway.
