[Pharo-dev] How to change my user name

For some reasons, I am LucFabresse in the last Pharo 3.0 that I downloaded. I'd like to restore myself, where can I change the username? (I saw way too much code related...) The menu 'System>Switch User' of course does not work if it ever was the answer (PanelMorph does not understand layout:) I know what bleeding edge means, but all these little annoyances divert me from the contribution job I assigned to myself :( Nicolas
