It appears that just installing the plugin, and by ignoring all of your compatibility instructions, bbPress 2.0 will inherit most of the Atahualpa style. For additional changes, it also appears that you can make adjustments to bbpress.css and accomplish most of what you need.
It’s touch and go right now, but I’m so thankful that you guys put this plugin together.
This may seem like a silly question, but I’ve read through many of the replies and haven’t found the solution. If I’m following these instructions correctly, and copying “/bbpress/bbp-themes/bbp-twentyten” into my theme folder (which happens to be atahualpa), would I modify the style.css in “bbp-twentyten” to make it a child?
If I’m modifying the style.css within atahualpa, how is it a child theme if you’re not asking us to make a copy of the original theme folder?
I’m having some compatibility issues with Atahualpa, which I’ll dedicate to its own topic (in case anyone else also needs the help).
