i have the master subscription how do i let my players use my source books?

1. Go to Collections >> My Campaigns
2. Click 'Create a Campaign'
3. Once you've made a campaign, click 'Enable Content Sharing'
4. Give your players the invite link for the campaign
5. Have them follow that link and make a character

As long as they have a character in your campaign and you have content sharing enabled, they should have access to all your books

Please forgive my slowness, but I am having trouble locating the 'Enable content sharing' prompt/button. Please help?

Make sure you have a Master subscription.  Under the "Collections" pull down on the home page, select "My Campaigns" page.  Now, click on "View Campaign" under the campaign you want to share to other players (or Create Campaign if you have created it yet).  You should then be able to edit and view your campaign.  There should be a light blue button with "Enable Content Sharing" near the top and right underneath the name.  Click it and then go the "Content Management" to select what books you want to share.

Master subscription is key.

Can you use content sharing if you don't have Master subscription though?

In order for content sharing to be turned on - someone in the campaign must have a Master Subscription - and they are the one that turns it on. Once content sharing is on though - all content owned by everyone within the campaign will be shared to everyone else in the campaign.
