The page now discusses the department's undergrad-faculty imbalance (public information), editorializing a little to say that this results in hardship for undergrads seeking academic career paths. Since this is a discussion of a shortcoming of our department, I'd like the text read by at least a few other grads to confirm that the phrasing is acceptable before putting it on a public page.
