According to the ?uselang=qqx command (see here for the example), the system message is called User-identity-box-edits-since-joining. Unfortunately, it is not whitelisted, so it is impossible to edit, unless if you can ask for it via C/G. However, the staff would most likely say "no", anyway. However, how they did it was customize that system message when any system message was whitelisted and customizable.
