User memobug wanted (and myself too) to have a way to restrict usernames to alphanumeric chars and underscore. To me it has been a headache with a lot of users because their password didn't work, just to find after investigation that their usernames had an space and they were writing it without it. I hope this helps others as it has helped me.
Here are the instructions to do it.
1) Go to your Admin Control Panel, Phrases Manager and create a new phrase named "username_invalidchars" in the "Front-end error messages" section.
For the text use something like "Username has invalid characters. Only characters allowed are letters, numbers and underscore."
2.- Open /forums/register.php
Somewhere around line 187 you will find the following
Add the following just below that
That's it, enjoy it.

PHP Code:
$errors = array();
PHP Code:
//--------------------------------------------------
// check username does not contain UNWANTED characters
if (preg_match('/[^a-zA-Z0-9\_]+/', $_POST['username']))
{
//eval(print_standard_error('error_username_semicolon'));
eval('$errors[11] = "' . fetch_phrase('username_invalidchars', PHRASETYPEID_ERROR) . '";');
}
