We've had individual buttons to click to add individual posts to your favorite bookmarking site for some time now (that chain of tiny icons in the bottom left of every post). But now I've added a way for you to bookmark the entire thread.
At the top of every thread is a dropdown link titled "LinkBack". This can provide you with a clean link to that thread, should you need it for pasting somewhere. But it also has direct links to bookmark the entire thread on your favorite social bookmarking sites, such as Digg, Google Links, Stumbleupon, Technorati, etc.
Of course, you need to be registered at the individual site for this to work. But if you have any idea at all what I'm talking about you probably already are.
Feel free to try them out. Every link will also let more interested people know about RetouchPRO, and that's not a bad thing.
