Setting your default search extensions permanently
You can save your default extensions permanently. That way, each time you start a new search, upname will offer you to search only these extensions. Of course, you can easily overwrite your default choice for each search.
If you are registered, go to your search preference page and specify which extensions to use as default for new search.
If you are not registered, click edit to open the extension selection dialog at http://upname.com/. Scroll down you check the checkbox that says "Remember this selection as my default search extension list" and click the "Continue with selected" button. UpName will store that selection in your browser's cookies.
