All seven gates of the Grammar Captive splash panel are now up and running.
It is not quite as good as I would have liked and tried to accomplish, but there is a limit on how much time one can devote to any single task.
In the end I believe that you will find it quite satisfactory. For now, the user can easily click his way through the totality of Grammar Captive in a well-organized fashion without ever truly entering the site.
Any further refinements will come at a much later date.
