In a Contribute site, you manage underlying file and folder permissions directly on the server. For more information, see Contribute file and folder permissions on the server.
When you set up a site, you must give users read access on the server to the /_mm folder (the _mm subfolder of the root folder), the /Templates folder, and all of the folders containing assets that they will need to use. Its also a good idea to give users read access on the server to the /Templates folder.
If for some reason you cant give users read access to the /Templates folder, you can still make the templates available to users.
If you take this approach, dont use site root-relative links in the subfolders. Site root-relative links are relative to the main root folder on the server, not to the root folder you define in Dreamweaver. Contribute users cant create site root-relative links. For more information about site root-relative links, see Understanding document locations and paths.
If links in a Contribute page appear to be broken, its possible that theres a problem with folder permissions, particularly if the links link to pages outside of the Contribute users root folder. Check read and write permissions for folders on the server.
