Weather.com has a free xml service for
adding weather on a website (albeit with some restrictions).
Making a vB mod out of this would be awesome. Somebody did a good bit of work on the weather.com xml and offers his script on
this website.
I can probably rig up something on a static (non VB) page but am throwing this out here because I don't have experience with making a vB product or plugin.
Eventually for my own uses I'm going to have a drop down menu instead of text input.
