I downloaded the executable, and I have a friend who is willing to send me some BTSX to try it out. However I can not register my name until he sends me some BTSX, and he can not send me BTSX until I register my name. Interesting deadlock.
Forgive the ignorance, but since this seems very different from Bitcoin, and I don't want to mess anything up.
Also I noticed there is account owner key, but then there is also account address. Which is very confusing. I had him try send to both of these, but no transaction is generated.
