Make Whozat your default search engine in IE, Firefox or Chrome browsers
To add Whozat to the search engines that you can use from the box in the top right of Internet Explorer (IE) or Mozilla Firefox, click on http://www.searchplugins.net/pluginlist.aspx?q=whozat&mode=title and click on I for Install. You can choose whether to make it the default or not.
To do the same for Chrome, go to the Settings menu at top right (looks like pliers), choose Options, make sure you are in the Basics tab, click on Manage next to Default search, click Add, enter Whozat into Name, w into the Keyword field, and http://www.whozat.com/search/?oneboxname=%s&search=Whozat+Me&src=Chrome into the URL field. Then click OK, select Whozat in the list of search engines and click on Make Default.
