You can use notepad to open the files; however, I find that confusing at times because of the word wrap and no definitive lines. I use winvi32 for all my "notepad" style editting.
http://www.winvi.de/en/Once open look for and change the following code to match the specific news site you would like to change it to. This should be done *before* you add the plugin. After it has been installed you will need to edit the vrWeb table under the miscData section which can only be seen when you switch to advanced brain editing mode.
HalBrain.AddToTable "vrWeb", "PatternMatch", "*Hal Help*", "welcome.html"
HalBrain.AddToTable "vrWeb", "PatternMatch", "*local weather*", "http://uk.weather.com/weather/local/ITXX0067"
HalBrain.AddToTable "vrWeb", "PatternMatch", "*local news*", "http://www.nytimes.com/"
HalBrain.AddToTable "vrWeb", "PatternMatch", "*yahoo mail*", "http://my.yahoo.com/"
HalBrain.AddToTable "vrWeb", "PatternMatch", "*zabaware forum*", "http://www.zabaware.com/forum/"
HalBrain.AddToTable "vrWeb", "PatternMatch", "*virtual humans forum*", "http://www.vrconsulting.it/vhf/"
When you first setup the file it should give you an option to specify which Weather site you want to use and your Zip code.
