Recently I wrote a post for TechNet Wiki Blog and pointed out that many resources can be found through the TechNet Wiki. So in case you want to check out what is available on TechNet Wiki around integration I suggest reading Integration is my business and business is good!.
I have been working on a couple of articles for TechNet Wiki last 18 months and published them. I am not the only one. There’s a lot of us in the BizTalk community for instance that have published and edited numerous articles. The number of BizTalk related articles on TechNet Wiki is close to 200 by now ranging from BizTalk versions 2006 R2 to 2013, general ones (common across versions) and Windows Azure BizTalk Services. You can access them from one place: BizTalk Server Resources on the TechNet Wiki. In case you have not yet bookmarked it then you the opportunity now.
If you like to participate in writing and/or editing articles feel free to do so. You will need to sign in or up and you all set to go. For guidance you can read Wiki: How to Contribute Content to TechNet Wiki.
