I;m sorry Bear, but I couldn't figure out which link to click to get the banner like yours. The only thing I saw with that picture was the PDA/Mobile graphic at the top left hand corner of the page.
I'm just now getting around to watching the "Creating the Lord of the Rings Symphony" that came with the Deluxe ROTK EE set. I learned how to play a DVD and use the computer for other stuff at the same time. Sounds trivial, but it's a HUGH thing for me! I enjoyed doing the chat view this way last night.
First, go to the main page, www.wunderground.com. Then, in the top left corner, enter your zip code and click the magnifying glass button; you should get a page detailing your area's current weather. On that page, scroll down until you see the current phases of the moon, not quite halfway down the page. Right under that, you should see a section titled "Add a NEW Weather Sticker® to your homepage!" with a description of the sticker and a link, "Click here for your Weather Sticker!". Click that link, and you should get a whole page of different banners and graphics with your area's weather info.
I'm sorry I can't give you a link to that page directly, but the link is different depending on where you're located; the link I get only works for Austin!
