From time to time I keep looking around the internet, blogs, articles and so to find new or more BizTalk Resources. There are some interesting videos for BizTalk Server available through BizTalk Server Development Center. Definitely something you can check out if you have not stumbled on it already. Other thing I found very use full is the BizTalk Posters. At my office at Motion10 there are loads of them on the wall. One l really like is BizTalk Adapter Pack 2.0 Interactive Poster (in Silverlight). Another thing I found today was a post by Thiago who posted or at least gives you pointer to BizTalk Visio icons, very handy indeed. So there you go more resources to add on the every growing heap of information.
