An "answer" consisting solely of a link is not an
answer, it's an
answer *. We only want
answers. So what should we do about it?
Compare the two questions. As pointed out in the comments, if a question can be answered entirely by the answer to another question, it's probably a duplicate. If it is, vote to close it as such. The answer in that case is largely irrelevant as the whole question should be closed quickly and eventually deleted. I wouldn't bother reflagging in that case, but if you care enough about your flag
weight count, a flag on it would probably be dismissed as helpful.
It is possible that the questions are sufficiently different. say two symptoms with the same cause. In this case, the answer is the problem. A proper answer referring to another question's answer should at the least
- Explain why the other answer is relevant
- Give enough information to answer the question without clicking through, whether explained in one's own words or quoted (use
- Cite the original answer
A link-only answer obviously does only one of the three of these. Now you have a choice: fix (edit) the answer or flag it and write up a proper answer that addresses all three criteria.
As pointed out by user12345, [this answer] presents a solution to that works for your problem. The other question's author was having trouble with his power couplings and you are asking about plasma relays, but the solution is the same because you both inverted the polarity in your flux capacitors. The way to fix it is to send a couple redshirts with it to the surface and nuke it from orbit.
