This module enforces the use of spaces in usernames, preventing single-word usernames to deter spammers. It allows administrators to configure which characters are required and how many times they must appear in a username.
We all agree that spammers don't use spaces in their usernames, right? This module forces users to use spaces in their usernames so that they can register, because this module initially doesn't allow one-word usernames. With the 7-x.1.1 version, you can now specify your own character and how many times this character should occur in the username.
