formatter on top of chosen formatter? (double-parse)

fysicsluvr

If I wanted to make a formatter that was applied to all comments on top of the formatter that they chose, how would I do that? (parsed by the formatter they selected, then parsed by my formatter) I see something in the documentation about ParseChildren; would I just use that instead of Parse? And how would I correctly add it to the StringManipulator so that it wasn't an option as a formatter, but was layered on top of the chosen formatter?
