Sorry, I realize I read that last post incorrectly.

I’ve dug into the code myself and have nearly everything working, but I’m unclear on the function for bp_signup_validate. In the WPMU plugin, there’s already validation checking for WPMU. Why not simply use:
add_action(‘bp_signup_validate’, ‘check_recaptcha_wpmu’);
?

For the WPMU code, this is called as a function:
add_filter(‘wpmu_validate_user_signup’, ‘check_recaptcha_wpmu’);

— and it looks like the same code you’d need for BP:

Am I missing something? Is there something else BP needs? It appears to me that the bp_signup_validate action lacks documentation.
