"HeinzJ"
thxs Anders, but that extension only renames users
whithin table "users"
an perhaps soome more. But my problem are the references within the
"cur"-table where you have text / links to a user page
"[[user:name]]".
these references dont get changed by that extension.

Use the 'what links-here' data and then run a bot to fix the refered pages?
