I would suggest an option to change either the registered email and/or the real name.
As it is now, you can not change neither the real name nor the email address you register with.
What if we change our last names or full names? What if we loose access to our email?
I also guess it will be required, as in Second Life, to "prove" your real life identity. Same rules for this community I suppose.
How will that work if we can not change the real life name given? Just a thought.
I don't think the answer I got from support, that I can register a new account as soon as Sansar goes open to public is a sustainable solution.
