I attempted to ask a question regarding "object-role-modeling" (it's a design methodology that doesn't get nearly as much attention as it should).

Unfortunately, when I wrote the question, I made a spelling error and assigned it to a non-existent tag "object-role-modelling". I realised my mistake, and changed the tag on my question. But the mis-spelt tag <a href="http://stackoverflow.com/tags/object-role-modelling/info">is still there</a>.

I do not want this tag to be in stackoverflow. I really want there to be more object-role-modeling questions on the site, and having two near-identical tags is just going to add confusion.

So, here we have the situation where:

 - There isn't a single question against this tag
 - The person who added the tag wants to remove it

Is there some way I can do this? If not, should there be?
