In response to a user request I have added the ability to search for unanswered posts. You can do this from the search drop down in the navigation bar at the top of every page.
Any other requests please let me know.
In the ongoing spam battle the forum is now checking posts against the Akismet anti-spam service. Hopefully this will improve spam detection levels and may even allow urls to be posted by people with less than 10 posts (I have not enabled this, will be monitoring performance).
