after sereral hours of testing and learning Linux a little bit i was able to run Zcash Swing Wallet UI
I like to ask for the settings after starting the real mining of Zcash
these setting must be changed after 28.11 but i don´t find any infos for this.

testnet=1
addnode=betatestnet.z.cash
rpcuser=username
rpcpassword=password

after changing this I have to create my real addr  ??
