Since memories-of-murders already has tag wiki info. I can't just edit the question's tag to memories-of-murder, as that info will not copy to the new tag. This is a request to merge or create a synonym of memories-of-murders » memories-of-murder.
EDIT: After posting this meta question, I've tried to post a question with the correct tag, memories-of-murder: What is the significance of the dialogue,"Have some meat before you speak" between Inspectors Park and Suh?
However, I can't submit the question with that tag and got this error message:
The tag [memories-of-murder] is too similar to [memories-of-murders]. If you think this new tag should be allowed, discuss it on meta.
