I've just gotten around to installing BBpress 1.0RC3 and everything seems to be working OK, except I can't figure out how to apply the eduBB theme.
I've tried dropping the folder into bb-templates where the readme informs:
If you wish to install more themes, you should create a new directory called "my-templates" in the base directory of your bbPress installation and install them there, not here.
So, I created a "my-templates" directory and moved the folder into that.
In neither case can I see the eduBB theme as an option in the Appearance menu. I can switch between the core Kakumei and Kakumei Blue.
