Sometimes people ask questions, such as "how do I do XY in ArcGIS?".
I occasionally happen to know a pretty simple solution in another software (usually QGIS), but do not know if it is right to give an answer, especially if there is no qgis tag in the question.
What is the policy on that, if there is one?
Now that I think of it, it is probably useful - the answer might not be the right one for the original asked, but later on might help other people who are searching on the topic.
