If it does - this is how I did it:
in the top right hand corner, under your name, there is an "add" button. choose "add discussion", which will take you to a new page.
Itried changing from filtered html to plain text - in plain text various html things appear - <P> for paragraph, for instance.
it took "forever" to preview, and (like last time) all formatting (again just paragrapf & linefeed) seems lost. Now posting w/o previewing
