Thanks much, Niketa. I was looking for the paste as link function under Share, but with your tip was able to find it in Explorer under the "shelf" side navigation area. Unfortunately, there still seems to be a problem! When I copy a folder from the original site and paste it as a link in the new site it doesn't show up for consumers of the new site unless they ALSO have full access to the original site. To be specific, here's what I did:
1. Created site A and uploaded documents.
2. Created site B.
3. Went to site A in Explorer and selected copy on a particular folder.
4. Went to site B in Explorer and chose to paste as link.
Now, the scenario is as follows:
1. Using Share, If I access site B with a user account (staff) that also has permissions to site A then I can see the linked folder in B and follow it back to the source material in site A.
2. Using Share, If I access site B with a user account (partner) that does not have permissions to site A then the space or folder containing the link displays the message "No items" on a red bar, which usually means that there's a problem with one or more items in the space.
3. I even tried setting permissions directly on the source folder in site A (via Repository browser) for the partner user account, but the link item is still not displayed to the partner in site B.
4. If I give the partner user permissions to site A (at the site level) then the link to the source folder in site A does display for the partner user in site B.
This is quite frustrating! I just want to selectively share content with someone without having to actually duplicate the content. It seems that a permissions-based system such as Alfresco would be able to do exactly that, but we're just running into walls at this point. Any additional help or suggestions would be much appreciated!
