You should try the light wallet. It's very powerful and not centralised. You could try and register the userame that you have listed here.
I sent Steem from my account here to the BitShares wallet and now I want to send it to another members BitShares wallet. I'm trying out the various faeatures.
I'll try it out later, when I have more time. Mostly Apps are only available for Android, but I have an iPhone.
OK let me know! Have a great day @freiheit50!
