Activate PMPro Users with Buddypress

functions.php

<?php
/*
 * This code allows you to use Buddypress' new user activation system in
 * conjunction with the registration system in Paid Memberships Pro. When a
 * user signs up, they will need to click on the link in their activation
 * email before they can login to your site.
 *
 * This code needs to be added to functions.php in your theme.
 *
 * Make sure that the Buddypress plugin is activated and the Activate page is
 * assigned in Buddypress settings.
 *
 * Make sure that the Paid Memberships Pro and Paid Memberships Pro - Register
 * Helper Add On plugins are activated. The Register Helper plugin actually
 * isn't necessary to get user activation to work... it is only used to assign
 * the Buddypress profile name field. User activation will still work if you
 * remove the add_pmpro_registration_fields and pmpro_set_bp_profile_data
 * functions.
