I've jsut found a British site which enables people to set up collections of poetry. I thought this might be an interesting development for Poemranker - people could arrange their poems into a specific order and ask readers to view the collection as a whole. Poets could get an idea of how to structure a collection, of how consistent their work is thematically and qualitatively, and might be inspired to try longer forms. 'Course this might use up all the memory in the world, but it's just a thought.
