I run three blogs that are full of figures, links and embedded iframes. ALL of it is done in MS Word 2010 (was on 2007 and it was simple to upgrade). I push one button in MS Word to chose categories, another to upload, another to jump to my blog's home page (hosted WP). All updates are done in MS Word, and a single button reposts them. All built into MS Word. I've tried all sorts of other, ahem, limited software, and nothing holds a candle to the built-in blog capabilities of MS Word IMHO!! There are a LOT of people in the Internet world with raw hatred for anything MS!
Any suggestions as to how to get WP to treat embedded HTML as html, and not turn it into text...would be GREATLY appreciated!
