Reviewing some of the old question I find questions with missing screencast (the link point to a missing file).
What are we supposed to do with these questions?
As a bit of general advice with links:
Of course, linked videos may go bad without recourse. StackExchange has it's own imgur (I think) for uploaded pictures, so that can be an alternative when the animated nature is less important (I'm not sure if GIFs count in this respect).
