I found that when creating a collaboration site in alfresco share, actually alfresco created a space for that site in the repository.
If I want to put some thing that is already in the repository but not in the site space, do I have a option to add a content as a link to the site reference to the content in another space in the repository instead of copy one to the site?
Does alfresco have the ability to create file's or folder's symbolic links across different repository spaces?
