Social Bookmarking (Webcontrol)
Adds social bookmark buttons for easy bookmarking to your web site. The control uses client-side JavaScript™ and AJAX to display a dynamic panel, where the user can select his/her social bookmarking service (as shown on this page top right). We have written this component because we got tired of slow, unreliable 3rd party solutions. Another advantage: this script does not use any Cookies or Flash Cookies. No third party servers are required - thus embedding this social bookmarking control is possible without any dependencies.
