Just a random idea, but changing the way pages are generated and named to implement hypens (-) instead of underscores (_) along with changing the default page (reset_pw to reset-pw) to follow suite. So upon creating a new page with spaces, by default these spaces are replaced with underscores where as hyphens would be the new norm.
I know there are a few big sites using underscores but generally the hypen is much more adopted, slightly preferred by search engines and easier I believe from a users perspective for typing…
Be interesting to hear any thoughts on the topic.
Cheers
