what is plasencia.us
This is pretty simple to do but you can only do it if the site has a search engines and the new Google toolbar installed on your computer.
1-First install the Google Toolbar software
2-Go to your favorite page that you want to make a button for and right click on the search box in that page. I believe it only works on web pages with a search engine on that page.
You then customize your button and presto it appears in your google toolbar.
Anytime you want to go to that favorite site. You just click the button and your there.
That easy and simple.
I must admit Google is impressing me.
