We have modified our code to allow you to organize groups. Previously only albums could be organized but due to demand we have expanded the feature to allow you to organize your groups as well. This can be important for people working with groups within groups. Simply log in and enter a group. You will have a left menu with a link to organize under the group name. You can then select albums and re-arrange them as you see fit. Please let us know if this feature is working well for you and if you have any other requests regarding functionality for the site.
Thank you.
