I am looking for a Question and Answer Joomla component/module.
There are some Yahoo Anser clones for Joomla but they're all commercial and cost quite some money.
I am looking for a free alternative.
All registered users should be able to ask a question; the admin or other users can answer.
I am not looking for a forum; just a simple Q&A system.
I am using Joomla 1.5.23 (not planning to update to 1.6 anytime soon).
