A rather new user self-answered their question. Yet not by adding and answer, instead the question was edited. See this example: Symfony 2 FOQElasticaBundle search on multiple Entities
My first feeling was to edit their answer out of the question into its own answer. Yet that would mean that I would post the answer and perhaps recieve up/downvotes on it. This made me think that this could be considered as copy-catting and rude.
Would it be rude?
Another approach would be to comment on the question to educate the user to post one's answers as answers.
How should we deal with this kind of answers?
