Well, Jp, I checked my line up on Time Warner/Bright House here. According to the web, channel 18 is the WB channel and I only found a used car salesman speaking in Spanish.
Some time ago, I told the powers at be to come get their box. I was paying for channels that I couldn't even receive. Alas, buddy. no preternatural for me.
But, thanks to you, I will check it out on the world wide web, and see what I'm missing.
