Delicious is a bookmarking site that allows you bookmark and tag your websites and access those websites from any computer. You can also share your bookmarks with others.
Delicious is fairly simple to use, you have to set up an account, and import your bookmarks. You can then edit and add tags and put tags together into bundles. I do highly recommend cleaning out your book marks first, it is much easier in Explorer.
The great thing about Delicious is that it allows you to share your book marks with others. You can gather a set of book marks and make them available to your students or teachers.
