Witch folder to install a buddypress theme?

Hello,

I read the themes manual and search the forum, but i continue with this doubts:

Witch folder to install a buddypress theme, like Fun Theme?

wp-content/themes?

or

wp-content/plugins/buddypress/bp-themes?

I have another question:

In Fun Theme "Components Settings", under theme settings, what can i do with the "SPAN Meta block" options?

Thank you
