Does anybody know who the author is or what the name of this nice script is? I browsed a lot of pages on the old web that make use of this script but I didn’t look into it then. Now, as always when actively searching for something, I can’t find even the slightest trace.
Please help me out 
Basic JQuery drag and drop functions can give you this ability.There is an old dollmaker script that has the drag and you can see how it is used and apply it to make a pinboard. I apologize it is not exactly what you are looking for!
i always use sadgrl’s drag and drop script for draggable divs. i’m not sure what kind of “pin” functionality you’d like, but w3schools has an overview for more specific destination drag and drop scripting that might be what you’re looking for?
These should do the job. I will have a closer look at both of these scripts and try to understand how they work.
Thank you very much!
