Import it with a simple .bat file to generate the <div>s and then insert it into TW. It's taken about 3 years to get to it's current form.
But it's TagglyTagging which is at the heart of the system. I'd be really interested in your experiences with using TT inside of a TW5 setup.
Although the current TT plugins seem to do an excellent job of listing the sub-entries, they don't appear to do so well in displaying the hierarchy, and grouping options which the original TT did. Now it may be my limited understanding of the way TW5 works, but if it needs complicated editing to make it handle all the options, then it fails as a system which any "Joe Public" could use. The original TT didn't need any fancy settings or options. Clicking the display options did everything for you.
That's the kind of functionality that is needed to get people using it.
