Why does wordpress 2.6.1 does not check for unique username? I have renamed my username from admin to something else for security. Today some user registered with username admin and then tried to reset the password.
After 2 hours one more registration occured with username admin. Luckily it was allowed. And again it tried to reset the password.
I want to ask, howcome wordpress does not check for unique usernames? And is it possible for me to ban this username from being used in future and also is it possible to make wordpress check for an existing username before it is allowed to be used again?
