How to create a new tag

Question

I would like to create a new tag. How to do it?

Hi Xiao Gang Wen, nice to see you here : ) A tag can be created by tagging any appropriate question as such.

In addition to what Dimension10 said, you have enough points to edit directly, so you can create new tags by just typing them and retag any question as needed.

@Dilaton yup, I wrote my answer when Xiao-Gang Wen still had about 310 points. Now after some imports of his posts, his rep has increased : )  

Answer 1

A tag can be created by retagging any relevant question as such, or for those without enough rep, suggesting edits for retags. For example, in the original revision of your post, you proposed to create the "topological-order" tag, so you can just select any question which is about topological and click the "suggest edits" button on it. You will be lead to a page where you can suggest edits, and you can suggest an edit in this format:  

{{suggest                   
  |post=6393
  |user=Xiao-Gang Wen
  |changes=Add topological-order tag. 
}}      

And someone with editing priviledges will approve it. However, you can see that this tag already exists.
