SmugMug has a wonderful feature called Sharegroups where you can create a collection of galleries for sharing. You can create as many of these unique collections as you want.
uSmug takes advantage of this awesomeness. Just enter the URL “tag” and password into uSmug, and you have the best way to view SmugMug Sharegroups on your iPad!
uSmug will be FREE for one week! Get it before September 1, after which uSmug will be $0.99/£0.69/download.
