It occurred to me whilst looking through some of the 'unanswered' questions that some of them have been answered, but the answer just hasn't been accepted because the user is inactive. I'm fairly new to SE forums, so was wondering what the policy is here? Is there are time-frame after which an answer may be accepted by a moderator?
I only ask because this will clearly be affecting the proportion of questions answered! Not massively I know, but it's a problem that will only increase as site-traffic also increases.
