Okay, so I was wrong in thinking the Poetry Wiki was gone. Now, go play with it before it really is gone. Shoo!
(I’ve already mangled “Invisibility” beyond all recognition, but you can do more! Make it a haiku!)
Edited to add: Alert!
Harry, who is a god among men, has restarted the Wiki here.
Please come play. There may be a nickel in it for you.
