Looks like
Chris has posted an
update to
PostXING.
Chris has indicated that this release "adds the ability to Load or Save a post
as a .htm file, as well as managing your blog (Categories, Post, Post &
Publish, Cross-Post, Delete, and plugins) from the Preview page." If you are
using .TEXT, then I recommend taking a look at PostXING for a client-side
posting utility.
