Sqworl enables you to create web pages where you can embed visual links to other web pages. Like gorgeous little snapshots of collections of sites. I don’t think the process could be any easier. After you have registered and created your **Sqworl** account, you simply log in, add a new “group” and paste the URL’s of the web pages that you want on your **Sqworl** page.
You are given a new URL for each Sqworl group page that you have created. Links to Sqworl pages can be shared conveniently from within Sqworl via email or your favorite social networking site such as Twitter or Facebook.
what makes it even easier is that Sqworl has a tool that allows you to put a button your toolbar "ADD to Sqworl" and when you see a page you like, click on a group....add a description (or you can do that later) then click ADD!
