Network Username Restrictions Override

Description

By default, WordPress network usernames cannot contain anything but lowercase letters and numbers. This plugin adds network options to let you include hyphens, underscores, or uppercase letters, if desired.

Furthermore, this plugin gives you the option to allow email addresses as usernames, or to allow all-numeric usernames (e.g. “1234”).

Finally, this plugin lets you override the minimum length for usernames (which defaults to four characters).

Why do my usernames end up in lowercase letters when I use uppercase?

Unfortunately, the WordPress code for adding users forces usernames to lowercase without offering an option to configure it via a plugin.

I have site URLs based on the username. Why don’t some of them load?

You’ll have to update the regular expressions in your .htaccess file if you use email addresses or periods in site URLs. The default WordPress .htaccess configuration does not allow them, nor will this plugin edit your .htaccess automatically due to the risk involved.

Does what it says!
