This just occurred to me as something which should be pointed out. There is no real direction in the FAQ or other sources about how to use concepts. This is going to be a work in progress as I work through them, but it is important to know the notes and direction for certain pages (which are usually on the pages themselves, but not listed when tagging them). Anyway here are some guidelines:
These should be tagged from comic book based movies. So please don't tag the Lord of the Rings.
Whenever one of these is tagged in an issue make sure to write on the issue page what it is an homage to.
For entire universes such as Star Trek or Star Wars, there should be only one concept page for the entire universe. There is no need for a Jedi concept page and a Force concept page as these are intrinsic to the universes. If there is a need to tag some like Jedis, it can go as a team.
Genres can always be tagged, as long as they are not too obvious. So stuff like Romance, Western, Post-Apocalytic and War are ok.
Object or team like concepts:
For instance Aliens and Robots do not need to be tagged every time and these fit more under the Object guidelines for tagging characters. Tag notable instances of their depiction, not every depiction.
This should not be tagged ever.
Tag these every time they show up.
DC Explosion and Implosion:
The tagged issues are as should be maintained. There is no need to add additional issues.
