I built everything as indicated, however, I have several questions.
1.) GUI wallet couldn't be started, if the daemon is also running. Is it okay?
2.) If I start the daemon and also the simplewallet, it can mine coins but they are marked as unauthorized. How could they be authorized?
3.) If I start the daemon, and start the GUI wallet on a different machine, GUI wallet couldn't find the daemon for somewhy. Ports are open, so that couldn't be the problem.
4.) Is GUI wallet able to mine at all?
