Performance Note
----------------
In email_registration_user_login_validate there is a query that can be slow
for sites with a large number of users. The normal query is required for
cross-database compatibility, but for databases that do string comparison in
a case insensitive way (MySQL) you can use a different query that will be much
faster.
To use it, you need to set this variable:

variable_set('email_registration_alternate_query', "SELECT name FROM {users} WHERE mail = '%s'");

Or in your settings.php

$conf['email_registration_alternate_query'] = "SELECT name FROM {users} WHERE mail = '%s'"
