+Gridster.js
+===========
+
+Gridster is a jQuery plugin that makes building intuitive draggable
+layouts from elements spanning multiple columns. You can even
+dynamically add and remove elements from the grid.
+

+
+Updating Begins
+===============
+
+Hi all, I have begun merging my fork with the main repository
+and am making some much needed fixes in the process.
+
+I am devoting an hour a day until it gets done.
+
+Thanks,
+
+Dustin

+=======================================================
+
+Gridster is not currently being actively maintained by 
+[Ducksboard](http://ducksboard.com/).
+
+I and others have been given access to the repo to help
+ maintain and address issues.
+
+I have created a fork of gridster that supports more advanced
+ features, like widget-swapping and static widgets.
+
+It can be found here: https://github.com/dustmoo/gridster.js
+
+Currently the code-base is different and I don't have time to
+reconcile the fork with this repo. 
+
+If anyone would like to help me improve my fork and reconcile 
+it with the main library I would be happy for the help.
