We've had a number of interesting questions on M&TV lately where the same essential question was asked and extensively answered on another SE site, specifically our sister site Science Fiction and Fantasy.
For a specific example:
This M&TV question: What happened at the end of The Thing (1982)?
Which has this SF&F answer: Ending of John Carpenter's The Thing
OR
M&TV: Why was the DeLorean covered by ice?
SF&F: Why was the DeLorean in Back To The Future not always covered in ice after time travel
Summarising the SF&F answer seems redundant to me and I suppose I could copy the answer (as a Community Wiki) with attribution but that seems equally redundant.
Then again, even a copied answer on M&TV is a resource for our users going forward.
What are the community's thoughts... is there an ideal or preferred option here?
