Problem Collections are a way to make arbitrary groups of problems. These are used in a variety of ways, both public and private.
Exploring Collections
You can search the full list of public collections.
Create a Collection
Any user may create a new collection. Some notes on the fields:
- name -- pick a short and distinctive name
- description -- more detailed information about the collection. For now this is text, but will be rich text later.
- type -- pick the best overall type of the collection. This just helps people understand the broad purpose.
- privacy -- who can see your collection in any of the places collections are visible. "Public" means anyone can see. "Private" means only you. "Friends" is your friends on the site. This applies to the collections search page, but also the problem page, and any other place collections may be seen.
- collaboration -- who can add problems to this collection. "Problem Author" is the default, meaning whoever creates a problem can assign it to this collection. If "Private" then only the creator of the collection can add and remove problems. Note: site admins and editors can also assign collections to problems.
Adding Problems to a Collection
From any problem page, expand the drop down, then click the "Add to..." button. You will see this:
Favorites have been merged into this interface. (In the future they will just be Collections.)
Selecting the drop down shows you options of what collections you can add.
Removing Problems
In the same "Add to..." drop down, you can click the x next to a collection to remove this problem from it.
Collections on the Problem Page
They show up as a list of links:
