Recently I've found some old questions which do not contain any code (usually just a link). Some of them have an accepted answer.
Since these questions are off-topic (according to the FAQ), should I try to ask the author to post the code to the site too (even if it seems meaningless since the OP has not been on any Stack Exchange site for months)? Should I flag or vote close on these questions?
Edit (2013. 11. 07.): Please note that this question was asked before the current Closed Votes queue (which does a great job) and there was not any attention of close votes on old questions.
