The article describes how to collaborate with someone else when using the Universal Scrolling Frames extension with Adobe InDesign.

  1. Everyone planning to export the document needs the extension installed (if not exporting to in5).
  2. When an additional person opens the document, (s)he must turn one scrolling frame on/off on their system. This will add any necessary CSS to the various exports (EPUB, Publish Online).

Note: There will still be an warning because the file pointing to your system is not found, but it wont affect the output.

To export an InDesign book with Scrolling Frames, see this post.
