Okay kiddo, let me teach you about associated signature containers.
When we want to send a letter or a form online, we sometimes need to sign it to show that we really mean what we're saying. Often, we use a computer program to sign it, and that program puts the signature in a separate file called a signature container.
But sometimes, we need to send more than one document together in a group, like a family of papers. And if we want to sign all of them at once, we need to have all the signatures in one container, like putting all the family's papers in one big folder. That big folder is called the associated signature container.
So, when we have an associated signature container, it's like a big folder with all the signatures we need for all the documents in the group. It makes it easier and faster to sign all the papers at once, instead of signing them one by one. Isn't that cool?
