Re: Sneak peek at bbPress.org 2.0
There have been talks about retrieving Sam’s work and getting it done, but I doubt it’s a priority. Consider it to be planned for ‘further down the road’.
bbshowcase is not an official part of bbPress (i.e. no direct affiliation with Automattic); I believe it was once maintained by an active bbpress community member and plugin contributor, who sadly does not think as highly of the project any longer.
