For everyone who didn’t know about it: The guys who ‘rule’ the Sitecore Yahoo-group, have decided to make it public, so you can use functionality like RSS-feeds.
Next to it, I’ve found another Sitecore-blog. It’s from a guy Peter J and his blog is called Usoniamdream. His first post is all about Porlets, so it could become interesting! 🙂 Altough he hasn’t post anything recently, he might will do after my post! Good luck ‘on writing’, Peter.
