Just observed that there is "Answer a Question" space available on the right side of every sub category where the new unanswered questions are displayed which makes it easy for you to shift your focus to unanswered questions easily.
Thanks for the feedback on the 'answer a question' widget. It was just released last night. We are testing it in the Firewalling, IP Telephony, LAN, and WAN topics at the moment. The plan is to roll it on the remaining topics very soon.
