Guild Wars 2

So I think I was told when registering with the game, that if you choose a name that is already taken then if you meet someone else from another realm, then the four digit code will activate at the end of your name. I think I am correct in that?

I took a name which was it seems already taken ankitten ow using a name which will put me in a position of having four digits at the end of my name potentially during gameplay and in a leaderboard?

I wish that I was given the option when creating an overall account name to be informed that a certain name had been taken, so I might try and find another original name without four digits at the end.

I understand that in the scheme of things this is not important, that said thank you for any reply on the matter.

Every account name has 4 digits at the end regardless of whether someone else has the same name or it is unique.
Support only changes the account name for security reasons for example if someone used his real name.

Ah. Thanks very much.
