If you have an iGoogle home page (go to www.google.com/ig if you don't), you can add a frequently updated feed from the IPE Blog so that you always know when new information is posted here.
Here's how you do it. Once you've created your iGoogle home page, click on the Add Stuff link in the upper right. Type "international political economy" into the Search Homepage Content space and then scroll down to the bottom of the results page, where you will find ipeatups.blogspot.com . Click the Add it Now link and you are in business.
You might also want to do the same thing for the Politics and Government's excellent blog. Search for "politicsups" on the Search Homepage Content page to find the PG blog.
