Hi onceuponatime,
Remember, this is just a prototype system. All this identity stuff, is just temporary till we get a more safe, secure and guaranteed verification process of who you are, which we plan on shortly providing with the new Bithsare Vote stuff.
As it says, the address fields are not required. Perhaps you could, for the time being, just provide one of your Bitshare IDs, so we can all know who you are, until we have this prototype system replaced. Or, you could, for the time being. Just provide a psuedonymn. Just think of this as the temporary test net version for people to play with and learn how to use/design, till we get the real Bitshares verification system wired in.
