Please remove the block on similar urls in regards to pages, custom post types, and taxonomies. I forget about this all the time and when I remember it forces you to use bizarre, inconsistent directory names.
I understand it is well intended to prevent slug conflicts, but seriously, what is the likelihood that anyone in their right mind would actually name a post "page/2" ?
Maybe just change it to a warning like bbPress is doing "Possible conflict with "X-Title-Name"
