Wikipedia is a community encyclopedia, so anyone can "do" the main page for Underworld. If you see something that needs to be changed or fixed,
be bold, and make the change yourself.
I'm not sure what you mean about the darktrain.org listing though. It's listed in the External Links section, and several references in the main articles are linked to darktrain.org. Some of the links and references listed in individual album and single articles still reference dirty.org, unfortunately, and need to be changed.
