BuddyPress.org

Hi,

Anyone know why registration templates doesn´t load from my parent theme?
/my-parent-theme/buddypress/members/activate.php
/my-parent-theme/buddypress/members/register.php
I copied them from \buddypress\bp-templates\bp-legacy\buddypress\members to my parent theme, customized them… but they don´t load in register and activate pages.

WP 3.6 Mu (network installation, subdomains)
BP 1.8.1 (BuddyPress Main site is not blog 1, define ( ‘BP_ROOT_BLOG’, 4 ) in config.php
Parent theme: no BP support, it doesn´t have add_theme_support( ‘buddypress’ )
Child theme: no BP support, it doesn´t have add_theme_support( ‘buddypress’ )

So I think I´m taking advantage of new BP theme compatibility and new BP template hierarchy:
buddypress.php from my parent theme is loading nice in activity, groups, forums, members.

Thnaks in advanced
