A few months ago, I complained that I couldn't register the domain name "InterplanetaryMovie.com" because someone else already owned it. But that someone wasn't using it.
The domain registration in question recently expired, and thanks to a heads-up from Trap, I was able to purchase it from name.com.
So www.InterplanetaryMovie.com is now the official URL for Interplanetary, as it should be.
Next mini-project... coming up with a clever "corporate" site for "InterplanetaryCorp.com."
