Interesting to hear the name broken down like that, I must admit that I was pronouncing it as aunthor-zelasttic, if you know what I mean. Perhaps you could look at adding a hyphen to the name aunt-hazels-attic, would help idiots like myself get a better grip on it.
Seems to be quite a common theme with eBay names now, 27 words all strung together. I know it's quite difficult to find a decent eBay id that is still available, but the name can often get lost in translation when multiple words are used.
It actually highlights a very important marketing tip, never assume the customer knows just because you do, always look at everything through the eye's of a customer.
Btw, changing your eBay id doesn't effect your feedback score. You only start again if you open a new account, so you'll maintain your 20 points.
