A bug and a question about Q&A

Hi all,

Two things that I’d like to enquire about:

# When I click to accept (or un-accept) an answer, I get the following error (before someone suggests it, I’d rather not turn WP_DEBUG off):

Notice: Undefined variable: id in /home/test/domains/test.com/public_html/test/wp-content/plugins/qa/core/votes.php on line 205

# Is there any facility to add comments to questions/answers, like Stackexchange? I don’t think the Q&A system works if users can’t make comments about questions before posting an answer or conversing with an answer made.
