Integrate Sign Up Code With the BuddyPress register page

Hi,

I have the sign up code plugin active on my site, but it only shows up in the standard wp-signup.php page and not on BuddyPress' register page.

Since I want to use the BP register and all of it's functions, but I still want to restrict sign ups to people with the sign up code, how can I get the plugin to work on the BP register page?

I tried to look at the plugin code to see if I can manually add the info to the register page, but I quickly found out I am an amateur at best and have no idea what I can do.

Thanks!
