How do I activate the bbPress theme?

Hi, I have a Multisite with buddypress installed and I just installed the bbpress forums on the site using the one click installer. I got the Edublogs theme for my site and I thought it would be nice to have a fitting theme for the forum.

But I have no clue on how to activate the theme for the forum. I have uploaded the eduBB folder to bb-templates as the installtion instructed. But after that I don't know how to proceed since I can't find a way to activate it from the dashboard.

Thanks in advance
