A bit confused here. Just registering for an ebay account as I closed my original one a few months ago. Just as I was about to post and list my item I noticed that they had given me a user name. Nowhere when I was registering was I asked to supply one or chose one, so I am wondering whats going on? I have since changed it to one of my own choosing, but am now a bit worried as to whether to list my item, security worries etc.
