Tethyring Content from Find Stuff
One way to get content into your account is find it in Find Stuff and Tethyr it there are two ways to interface with pGroup / pList that you find in Find Stuff.
Subscriptions
You can subscribe to a pList or pGroup. When you are subscribed all the content that is added to it gets added to the pList that you specify after the subscription.
Child pList / pGroup
A child pList / pGroup starts out as an exact copy of the pGroup / pList when you Tethyr it. From there you have different functions to keep the pList / pGroup in sync or decide when you want to sync it up.
For a deeper comparison of these two methods and examples of use cases for each, check out the Advanced Tethyr’n page.
