Er, before you get too far on this, check to see if your database
already does this without you realizing that it does.

For instance, MySQL does case-insensitive VARCHAR and CHAR lookups
unless the column type is marked BINARY or you cast the type to BINARY
in your SQL query.

For instance, 'chris' = 'CHRIS' in MySQL inder normal circumstances.

Primary and unique keys respect this behavior, too, so I can't have
"chris" and "CHRIS" as two separate usernames in my user table where
"username" is a UNIQUE key.

You might be able to save yourself a lot of trouble.
