How to get an actor's birthplace corrected?

I am part of an online "Northern Exposure" fan group, and we would like to get an error in William J. White's listing corrected. William, who played Dave the cook on the series, was not born in Scotland. He was actually born in West Seattle, Washington, USA. Accuracy counts, so how can we get this changed? There is no direct contact information on the IMDb site that I can find. Thanks.
