The CO-ODE news pages are generated using a technology known as RSS.
RSS provides a feed that can be read using an aggregator, which allows you to get the latest info without having to subscribe to a mailing list. Many browsers and mail clients already support this technology.
An example of this is Firefox's Livemarks:
- select Bookmarks->Manage Bookmarks to get the bookmarks dialog up
- select File->New Livemark... and copy the address of the feed from here into the Feed Location box
- the feed will appear in the list with a symbol, and containing all the most recent news
More aggregators/readers can be found on http://www.ourpla.net/cgi-bin/pikie.cgi?RssReaders.
