using Blogsmu 1.2.2., WP 3.1 and BP 1.2.8 the Q&A is displayed on the left of the 'left' sidebar, pushing it over to the right.
It also does not display answers, although setting are defined to 'view answers' for all relevant user groups.
When submitting an answer, the screen remains on the editor (now empty), but answers won't show. Answers are not counted in the answers counter, but in the contributors counter.
clicking the link on the contributors counter throws me out onto the main page (home), but does not show the contributors profile.
(maybe this thread should be cross referenced in theme support for blogsmu?)
as pictures say more than a thousand words I attach two screen shots
