CUNY Academic Commons

The issue with post content - rather than post title - being used to construct the strings you see in the activity stream, was fixed in bp-multiple-forum-post a few months ago but never merged to the Commons. https://github.com/cuny-academic-commons/bp-multiple-forum-post/commit/4608641b88b47a81389137ed38d5813407aff109 I've backported to the Commons in https://github.com/cuny-academic-commons/cac/commit/11464f198420b1bec0d2ebba2e3ca387c5c4ff0a

Your observation in 2 isn't quite right - forum thread titles don't appear in the interface for any topics, regardless of whether they were involved in crossposting. This dates to https://github.com/cuny-academic-commons/cac/commit/063d77d03f3e96ecaa13f8176bc00bbc5f316e05, which was part of #3177. It appears that the logic here was that the /forum/ page for a group does indeed have a duplicate header, but it didn't take into consideration the title on single topic pages. I've made some modifications to fix this. See screenshot.
