<a class="clsStd" href="/techref/objectmodel/objects/users/index.htm">Users</a>.Inviter Property
Returns a User object that identifies the user who started an MSN® Messenger chat instance. This property is read-only.
This property identifies the user who originally began this Messenger conversation.
To determine whether the local user initiated this conversation, test for the equivalency of Users.Inviter and Users.Me.
Displaying the inviter's name is implicitly restricted because the Name property of the User object needs the PassportSiteID permission flag.
