New Problem With name checking...

[{Makenzi}]

I modified register.php to check is username is valid and here is my problem: It allows registration even if there is ! near username ( invalid username )...
Here is check
This number != 1 was != 0 but it won't work with != so this green check works but it allows invalid name (Example name "Name" is not valid and it says its not valid but it registers user... )

if (preg_match('/^([A-Z]{1,1})[a-z]{2,9}+_([A-Z]{1,1})[a-z]{2,9}$/', preg_replace('~&#(?:\\d{1,7}|x[0-9a-fA-F]{1,6});~', '', $context['checked_username'])) != 1 || $context['checked_username'] == '_' || $context['checked_username'] == '|' || strpos($context['checked_username'], '[code') !== false || strpos($context['checked_username'], '[/code') !== false)
$context['valid_username'] = false;

{
    return preg_match("/^[A-Z]{1}[A-Za-z]+_[A-Z]{1}[A-Za-z]+$/", $name);

//This - New code i added...
Problem is this:

Even if I see that symbol, it allows me to register when i click register button...

Your code may need to be duplicated into Register2().
