Each organizer with an account on the Action Network and each group has its own repository of files for public download.
To access your own files, choose Upload Files from the People tab in the Start Organizing menu. You can then access the repositories of group's you are an organizer in by choosing them from the Currently Editing drop down menu in the upper right. Choosing another repository will redirect your browser to the correct URL.
To access the files of another organizer or group you are not an organizer in, click a link they've provided to their files.
Note: The files system is meant to hold files you would like others to download, such as PDFs or graphics activists can use for themselves and to host files you want to display in your emails or similar uses.
