Display BuddyPress fields on Signup page/Plugin manuals??

Hi,

I’ve got the membership plugin working on my site… Just confused about the additional plugin/shortcode stuff and BP integration…

How does one display the extra profile fields on sign up page?

And, there seem to be LOTS of cool extras like, Gravity forms, Contact form 7, WP Audio, etc… but I have NO idea how/where to use them. Is there a manual available so that I can teach myself?

Thanks for your help!

Simon
