I've been playing with a little webapp for tags of a certain kind for travel.SE (current pre-alpha version gist on github).
One thing I would like to do is add links for the various tag-related functions on the actual SE site for each tag.
But I realized that the while most tag related URLs use the tag's name, the edit URL uses some internal tag ID. For example for the codeigniter here on StackApps we (currently) have this URL:
Now the thing is I can't find anywhere in the API that will provide either this ID or this URL. Have I missed something or is this a feature I should request for the future?
