By default, any Subscriber List you create is only visible to you. However, if you'd like you can easily make it so other users can see it.

1. Go to your Subscribers Manager

   This is located here: Subscribers Manager

2. Find the Subscriber List you want to share

   You can use the Campaign drop down to navigate to each of your Campaigns, or Unassigned (those that have not been assigned to a specific Campaign), or choose "Show All". Alternatively you can use the Search input to search by Subscriber List name.

3. Click the Tools Button

   Once you've found the list you want to share, click the Tools button. The Tools button will reveal several options. One is "Edit Settings".

4. Select "Edit Settings"

   This will reveal a modal window which will allow you do several things. One of which is to share.

5. Click the "Share" checkbox

   This will make so the current Subscriber List is visible to other users.

6. Click "Save"

   Now other users can see AND USE your subscriber list. This would be very handy for a number of things, one of which would be sharing Test Lists.
