I want to know how to create a new tag on Stack Overflow. Where is the entrance of this function?
Please post a screenshot for me. Thanks a lot.
You need 1500 reputation on Stack Overflow to create a new tag. Unfortunately, you don't have that much yet.
If you did have 1500 rep, then you could create a new tag simply by adding the tag to a question. The tag will be created automatically.
You edit a question and type in a tag that doesn't exist, so long as you have the create tag privilege.
