Letting others edit content you created
Both Jane and George have been hard at work creating pages in the Documentation folder. Jane has published the Documentation folder and several pages:

Jane has decided that she wants to turn over all editing (but not publishing) control of the "Documentation" folder to George. So she returns to the "Documentation" folder and clicks on the Sharing tab:

From here she only needs to tick the "Can edit" check box and George will be able to edit all the content in the "Documentation" folder -- including the "Documentation" folder itself. When George next visits the folder and clicks on "Project Overview" (which is a Page that Jane created), this is what he sees:

So now George can edit any item in the "Documentation" folder regardless of who created it or when.
Meanwhile, Molly has joined George as a new team member. George helps Molly start updating the "Widget Installation" document. He goes to the sharing tab for "Widget Installation" and searches on Molly's Full Name (not username) and gives her the "Can edit" permissions on this document.

Now when Molly goes to the "Documentation" folder, she can see the two published items and the private item that she is now allowed to edit:

And, in fact, when she clicks on the "Widget Installation" document, she is able to edit it:

Notice, however, when she clicks on either of the two items she isn't allowed to edit, she doesn't have any additional access. She can view these two items because they are published and in the default Plone workflow (meaning that anyone can view them).

One final note on this example: if the "Documentation" folder was not in the published state OR Molly had not been given any other permissions (for example, "Can view" on the Documentation folder), then Molly would have needed the complete URL to reach the document she had been given access to edit. Permissions are very specific in Plone!
