Sacha Dawes: “One of the more common requests we receive from you regarding management pack availability is to communicate when new and updated releases become available. While we are looking to improve such an announcement capability in Pinpoint (the site of our new System Center Catalog – see my earlier blog for more information) the product team recently created a Twitter hashtag, #mpreleases, to help communicate of new and updated management packs.
Of course, given the open nature of Twitter it’s not just for Microsoft to leverage. Our partners, such as members of the System Center Alliance, MVPs, and more, can also leverage Twitter to announce and post links to more information about their management pack releases.
For more information on Twitter, check out http://www.twitter.com. Details on hashtags can be found here.”
I checked the #hashtag but no releases yet via the #mpreleases hashtag. Only the announcement :-)
