If you want to get more followers on your collections, you may want your readers to subscribe to new collections once created. You have three options for this section:

• From blog page only: allows your readers to subscribe to the new collection only on one location: the specific collection.
• Show a list of all Public blogs allowing subscriptions: allows your readers to see a list of all public collections which they can subscribe to from any of your collections.This option is checked by default.
• Show a list of All blogs allowing subscriptions: allows your readers to see a list of all blogs which they can subscribe to from any of your blogs.

Your readers are free to subscribe to any of your collections but you may want to strategically target different primary audiences by checking the option that serves this purpose.
