Shared, private-on-first-use views
A "Shared, private-on-first-use" view begins as a shared view and becomes a private view as soon as a user accesses and saves the view. These views give you a convenient way to distribute personal views to multiple users. You usually create this type of view by using @UserName to customize the display for each user.
Note that this is the only way to make a view work with @username, because the view selection is only parsed when the view is generated. Thus, if Tom opened a shared view that keyed to @username, all of Tom's documents would display. But, if the view is still open when Jay accesses it, Jay sees all of Tom's documents, and does not see his own. So, to avoid this conflict, designate the view as "Shared, private on first use" when using @username in the selection formula.
