I was editing a question and tried to add a "iphone-5s" tag and AD won't let me do it. I have the rep to create new tags, but I guess not if it is too similar to an existing tag.
I was trying to update this question: What's the difference between the battery of iPhone 5s vs iPhone 5?
Also, a tag for iPhone-5c will probably be necessary shortly.
Is there a way to create these tags, or do I need to ask the moderators nicely?
