To create a tag you need at least 1500 reputation and need to ask or edit a question and add the new tag to your question, this is clear.
like JoseK said in this post: How to add a new tag on Stack Overflow?
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.
Now I want to create a tag, so I want to ask a question which is not related to any problem. Is that possible, or this is not possible and a bad idea?
Or is there any other way to create a tag?
Any clarification about this answer here also?
like what they say here:
If you have enough reputation to create the tag, and if you think there is a clear need for a tag, go ahead and create it yourself. If the new tag causes controversy, you can always come back to your site's meta to ask the community to judge it.
So is there another way to create a tag, which I don't know of, or what does this mean?
