Should answers be a synonym of responses? The "answers" tag has no tag information, and has been misused to tag questions that are asking for answers (or corrections to answers) for practice exam questions. The "responses" tag has a description and is more likely in my opinion to be associated with questions about the grammar and phrasing of responses to questions.
I do not have enough reputation in responses to suggest the synonym - someone with at least a score of 5 or greater in the tag and 2500 reputation would need to suggest it.
