I'm sorry, but there's nothing I can do about it at the moment. It affects all answer sites (such as Xbox Answers and Music Answers). I believe it has something to do with Wikia's recent update to how categories are handled. I've already filed a bug report, so hopefully it will be fixed soon. In the meantime, it is still possible to answer questions if you add Edit to your tools menu. I am not me (talk) 03:41, February 7, 2013 (UTC)
I've found that if you disable the "Category" module in your Preferences, the form to answer will return. Hope this helps. Thank you for your interest in answering questions on Wikianswers. I am not me (talk) 04:55, February 7, 2013 (UTC)
