I have to admit, this module caught my eye as far as looks, and I decided to have a look.
The instructions on the site indicate to drill down to your weather page - and look for: a url with the following format weather code: ASXX0075
Unfortunately, at least for Halifax Canada, the yahoo page does not indicate such a code. It would appear that Yahoo has taken steps to hide this code, perhaps after the author wrote the tutorial.
I am taking further marks from this module, because it uses a data feed thats in my opinion utterly useless.
-the weather data is based on the weather channel (weather.com) and I have found that (at least for Canadian cities) the weather couldn't be farther from what environment Canada reports (inaccurate) - always, so when I saw that yahoo was getting this feed themselves from weather.com, I knew I would not be utilizing this module on my site at that point regardless.
- Just a heads up for anyone that wants to use this on a Canadian site - weather data VERY inaccurate from weather.com!
