I've posted a new WikiTalkExperimentalBuild on www.flexwiki.com.  This is the software that's now live on the site.  This includes everything needed to make the full FlexWiki UI be based on WikiTalk -- the original goal of the WikiTalk project.  I've started to do the documenting of the new features involved (both directly WikiTalk and related features that I had to build along the way -- including TopicBorders and advanced TableFormatting).  More over the next couple of days as I have time.
