# Why don't we have a Coordinate Geometry tag?

I recently came across [this] question and thought that it should be tagged "Coordinate-Geometry". However, to my astonishment, no such tag exists. Why is it so?

I finally created that tag. I do not know the formal procedure for a tag creation. Does just putting it to a question creates a tag or do the mods look at it afterwards?

• In the case of Meta, honest questions almost always deserve to stay. Someone else may have a similar question with regards to some other tag, and in which case I will not have to re-write the answer again if this one is available. :-) I always think it is a good idea for new users to ask about "stuff" on meta. It keeps us on our toes about what we consider "obvious" and "well-known" and "settled". And it helps make the whole site more friendly to new users. – Willie Wong Sep 23 '13 at 12:40
