I did a couple searches and couldn't find reference to this. If I have a question that is not going to get answered because there is no way to handle what was being discussed, what do I do? Leave it unanswered forever?
An example is: Custom Button (javascript) - Field Name Changes Are Not Automatically Made
The request "can't be done" apparently because of what was discovered in comments under the one offered answer. I presume that it would not be simply deleted for the sake of others who may have a similar question and would be helped by finding this and knowing there is no solution (or was not at the time).
