OK. I will release it this week. However, existing accounts won't be affected. Are you OK with this? Moreover, since the URL fields in Account Settings are editable, if someone really wants to camel case something, he certainly can. It's just that the account, when first created, will use lower-cased scheme and domain.
Sound good?
edit: BTW, comparisons of schemes, subdomains, and domains when populating passwords/usernames will be case-insensitive. Rick, I'd appreciate it if you could register so I can send you emails of the forum if necessary when developing this change.
