BuddyPress.org

I have been poking around for a bit, but I am unsure which files we are suppose to be editing (css/html)

I understand custom.css, but its ok if I start hacking away at home.php, etc… right?

Do most people have only the sole buddypress-home/ folder per install?

And if you go to a different folder for the home theme, does it also have to contain the css folder with the css loader and such?

Just trying to figure out how others are starting.

Thanks

Matt
