Facebook Send Button for ASP.NET

Facebook Send Button is used to share info about interesting content with just a couple of (presumably) interested Facebook friends. For example, visitor of this website probably has a couple of friends which are also web developers, and they have much more interest in the topic like this then all other friends. The best way to share this info is for them to get it in their inboxes. That is much more effective than sharing on user wall. Facebook Send Button also has an option to send info to Facebook groups for which the user is fan of, or to any email address, so user can send it to people which are not in his list of Facebook friends. The control is available in C# and VB.NET programming languages, as part of Facebook (C# and VB.NET) ASP.NET Control library.
