As I said, it's bad for you not to change it, but it can't be helped because the dark skin is there and people will use it, and removing it would be out of the question. The only idea that just opped into my head could be, perhaps, changing the colour of the back of the username area (behind the text, not the whole bar including Join Date etc) to a very pale grey or perhaps just a slightly lighter grey than on the dark skin. That could work :/
