Well, when I made my first question I ended up making a tag nobody had used before. It said 'you can't create your own tags until you reach a certain amount of points', and I understood that.
However, it got me thinking.
If you made a tag like 'i-am-awesome', which has nothing to do to relate to the question, then what would happen to the user? Obviously, the tag would be deleted from the question, but would the user lose points or something?
