Perhaps this is not the place to comment about my concerns with the QA page, but there are some features that could be useful:
Possibility of editing other people questions or comments: There are really interesting questions, which can be improved in format with ease, e.g. LaTeX code, cadabra block code, etc. Inspired in stackexchange, one could use the number of points to limit the privileges given to people.
Vote up comments: Some times the discussion derived from a question/answer is as valuable than the question/answer. Those comments deserve recognition! Don't they?
