I made an answer for [Appropriate preposition to go with "concerned"](https://english.stackexchange.com/q/41587), and noted that although I acknowledged that *for* could be used, I didn't knew in which context.

In the meantime, Dan Ray proposed an answer which give said information. Would it be proper for me to edit said information or part of it? The concensus on SO.meta seemed to be that [it would be ok, as long as I give credit to the poster](https://meta.stackexchange.com/questions/17685/etiquette-when-is-it-ok-to-edit-your-answer-to-include-information-from-someone/17693#17693). But I can imagine that philosophy might change between the different StackExchange sites.
