What are some common pitfalls to avoid when setting up a PHPBB forum?

One common pitfall to avoid when setting up a PHPBB forum is not properly securing the forum against spam bots. To prevent spam bots from registering and posting on your forum, you can implement a CAPTCHA system during the registration process. 

// Add CAPTCHA to PHPBB registration form
// Open includes/ucp/ucp_register.php and find the following code:

'username' => request_var('username', '', true),

// Add the following code below it:

// CAPTCHA verification
$phpbb_captcha->init();
$phpbb_captcha->execute('ucp_register');

if ($error = $phpbb_captcha->get_errors())
{
    $error = array_unique(array_merge($error, $error));
    $user->lang['CONFIRM_CODE_WRONG'] = (count($error) > 1) ? $user->lang['CONFIRM_CODES_WRONG'] : $user->lang['CONFIRM_CODE_WRONG'];
    trigger_error($user->lang['CONFIRM_CODE_WRONG'] . '<br />' . implode('<br />', $error));
}
