I've read several times here that URLs should use hyphens rather than underscores to separate words. Example: /web-directories vs. /web_directories

If this is the case why on earth does phpLD create new URLs using underscores when using their multiple sub category add function??? Wouldn't this be an easy change for them to make? Or is the effect really inconsequential?

Also, I see a bunch of directories using the underscore vs. the hyphen so should they change to hyphens and add redirects or leave them be?
