Searching on Chrome says: To upload audio to the Digital Bible Library (DBL), you need to be a designated Content Manager for your organization; then you use the DBL's in-app uploader, a user-friendly tool for text, audio, and video, which guides you through descriptive and structural stages for files like MP3s (chapter-by-chapter). This process has replaced older methods like uploading via Paratext and focuses on providing metadata for discoverability.
So the question might be, who is a content manager for your organization?
