The EP Team has created a blog. Welcome team to the wonderful world of blogs.We have made tons of enhancements and a really cool ASP.net AJAX based EP framework in Microsoft Dynamics AX 2009 and we need more than one blog to talk about EP. This blog http://blogs.msdn.com/epblog is straight from the heart to the masses.  All the dev/test/pm team members are going to contribute to this blog. We are also in the process of creating and releasing number of EP quick start guides, screencasts etc. So get ready to be drenched from information firehose.
