Provides a form (with an associated permission) to allow a site administrator to assign a flag to another user for a specific piece of content.
Why would you need this? Here's an example use case: Suppose you're using the Flag Bookmark example that ships with the Flag module. You have a new employee starting, and when they log into the employee portal, you want them to see the most commonly used resources already bookmarked: employee manual, HR policies, etc. Instead of having to log into their account or use a solution like Masquerade, this allows you to bookmark the key content on their behalf.
