Comment (by Clorith):

 I'm in favor of the forced lowercase URLs, but i think it's important we
 add a note in the admin if we actually do have to enforce them.

 Users add emphasis in their URLs thinking it matters, when they might be
 hard to read or understand otherwise. If we keep forcing lowercase without
 any user feedback I suspect there will be some frustration out and about
 as they kee ptrying to update it a few times in a row and then take to
 Google and the forums.

 > Your Site and Home URLs have been changed to lowercase to ensure
 compatibility with other systems.

 I don't think explaining to users in broad terms what it means will help
 them, but this would be beneficial I suspect in other terms as well,
 suddenly their site needs to send an email to someone, and the receiving
 email system is case sensitive etc. (as most other services I've seen also
 convert the addresses to lowercase in my experience).
