MultiURL is another site that allows you to share multiple links to various sites in one simple link. When you create a group you can provide it a group name, group alias, and a password. The site starts with 5 possible URL's but you can add more with a click of a button. You can also give a name to each link as well. The final step is to create an account so that you can keep track of the MultiURL groups that you create. The links will never expire as long as they are visited at least once a year.
You can also create your MultiURL in batch mode if necessary. When you create your group viewers will have the option to have a toolbar to view the links which provides a view of the website or just multiple links on a single page. There is also a Wordpress plug-in that takes all the links in a post and creates a MultiURL group for your links. Pretty cool.
Another useful tool in education for sharing links with students for research or for an extension of a lesson shared in class. You might also provide links to web 2.0 websites that they can use to create a project. Using Justpaste.it you can include directions with the assignment. This could be a very useful tool for students and it is a simple and quick tool to use.
