Den in USA I found the "Thereden" nick in the data base :-). Small addition: If you are using Theremin v1.4 then you need to press Next button at least once in order to put the app to waiting-for-players mode. In Theremin 1.5 it is not necessary. Also the "Network status" should be "Logged in". If it is "Offline", one needs to check the Network Settings.
