Dear BB
The "Name" field corresponds with your real name, rather than a username. A username, much like a puppy, is not just for life.
You can edit the name field in case you have to change your real name - possibly because you're a spy or on the run from the FBI in a case of mistaken identity (or both!). We like to make sure these kind of bases are covered at The AnswerBank.
We do also use this in email shots and the like.
Also, I would remind you that AB was relaunched in September on a rather uneven keel! Little things like this are likely to be addressed in the future. If you have any usability feedback we always appreciate a fresh pair of eyes! Drop us an email here:
