**Be cautious with creating new tags**

> From [FAQ about tags](http://meta.math.stackexchange.com/questions/107/faq-for-math-stackexchange/128#128): *Try to avoid creating new tags. Instead, check if there is some synonym that already has a popular tag.* It's not easy to keep balance between too specific tags and not having enough tags, but tags for specific theorems are usually too specific, perhaps with the exception of some very important ones. (Of course, you can disagree with the removal of the tag you've created, and there is possibility for further discussion, if needed.)
