Flickr only had one level of sets, so you couldn’t group them which led to a very messy layout. Pbase, Smugmug and all the others already had this…so thankfully, Flickr has listened to it’s members and launched what they called “Collections”.

Today we launched what’s probably the most requested feature over the last few years: a way to categorize and organize your photo sets! In the past this feature has been referred to as “sets of sets” or “subsets”. After today, we’ll know it as “collections”.

What are collections, you ask? A collection is a container into which you can place either sets or other collections, allowing you to create a hierarchy as deep as 5 collections. You can place as many of your sets into a collection as you like, and a set can be in as many different collections as you like.

Even more of a reason to use Flickr now, I’m loving it!
