In 2009, we introduced the application contacts feature, which makes it possible for web sites to offer the ability to IM based on site-defined user relationships. Messenger users can chat with other Messenger users based on the relationships they have on web sites without becoming Messenger friends and sharing email addresses. Based on low usage of this feature, we have decided to remove support for application contacts in the Messenger Web Toolkit in six months. Core IM functionality will continue to be supported after this date.
We appreciate the feedback that users and developers provide on Messenger Connect. Please keep your questions and suggestions coming!
which core im functionality will be keeped?
