meta: advanced TypePad posting

TypePad posting has a lot more capabilities than I ever realized.  Including split postings (introduction plus continuation) and now Technorati tags in addition to categories (note: categories are also considered tags by Technorati).

To access these features, even if you have the lowest-end Technorati account (like me), just go into the posting screen, click "Customize the display of this page" at the bottom, and select either Advanced or the particular Custom features you want.
