My understanding is that generic system tags like dungeons-and-dragons or fate should not be used if a more specific tag like dnd-4e or dresden-files is also applicable.
For reference: How Should We Tag D&D Versions?, Does the [system-agnostic] tag conflict with system specific tags?, Cross-system Fate tag protocol, and Fate tag redux: The Archive Trawl Blues.
I've been seeing a lot of posts tagged both gurps and gurps-4e lately. I know nothing about GURPS, but the tag wikis seem to say that gurps is to gurps-4e as dungeons-and-dragons is to dnd-4e.
So: Do we need to excise gurps from these nine posts, and help people avoid double-tagging in the future?
