If you like lots of messages, and want to get messages containing new blog posts as they appear, you can subscribe to various-format feeds of the ESP Blog. For example, the URL for the RSS 2.0 feed is:

http://esp.alcf.anl.gov/blog/?feed=rss2

There’s a lot of software out there for reading RSS feeds. Some email programs, for example, allow you to subscribe to feeds, resulting in messages appearing in your mail Inbox when new blog posts go up.
