need help with ''[ ]''

You can try to use your Monitor keyboard from the Start Menu (Start -> programs -> fitings -> easy handling -> Monitor Keyboard), or when your Keys dont work, you can copy and paste it in your name.
Also there are Rumors, that when you already got these Brackets in your Name and change it, it wont allow you - i cant confirm that, but its possible, that that is the reason why its not working.. :rolleyes:
