hi korban

I had worked on the same concept and came out with my own plugin.

You can download it using the following link

http://www.thinkinginwordpress.com/download/bp-auto-activate-user-and-blog2.zip

Upload it to wp-content/plugins activate and it will remove the confirmation email.

It works with buddypress 1.1.x .Please note it will not work with buddypress 1.0.3

Hope it helps.

thanks
