Rockethound,
I'm glad you like the holistic grader. Spread the good news!

In answer to your (remaining) question, there is no automated way to remove a grading scheme. Depending on the situation, you may want to simply
revise an undesired scheme rather than deleting it. If that won't work for you, then there is a work-around:
- 1. Close Word and T.A. Toolbar, then;
- 2. go to your My Documents folder. There you will find a folder called "TaToolbar" within which are some xml files. Locate the one that is associated with the obsolete scheme and just delete it. It will no longer appear when you launch T.A. Toolbar.
I would urge caution when doing this, however, as this is not a supported use of T.A. Toolbar. Tampering with the files in this folder could possibly break T.A. Toolbar, so be careful. I would also strongly urge you to simply save the xml file in another directory somewhere rather than deleting it. (Just in case. . . . )
