Very useful after slight modification

Seems to work just fine after modifying the css to enable it to sit in the right hand column. This worked for me:

#buddypress #security-section.register-section {
float: right;
width:48%;
}

Plus the modification of one line in bp-recaptcha.php as shown here https://wordpress.org/support/topic/please-check-the-captcha-code-its-not-correct/#post-6704142
