Team Foundation Server Query - deleting Work Item Templates from server

Any TFS experts out there?

I've been setting up a new TFS project and in the process of copying and editing Work Item Templates using the (witexport and witimpoirt power tools) I created a template called "Bug Test" so I could try it out before using it in anger.

The only problem is that there doesn't appear to be any mechanism for deleting templates from the server. The only articles I've found on google only seem to relate to changing the templates available in a local folder.

Any ideas?

NB I'm using VS2005
