Today I released a new build of FlexWiki.  It's got some improvements (see the list of things included in ReleaseNotes1569).  More importantly, it's the first officially mainstream build of FlexWiki with WikiTalk; WikiTalk is no longer in experimental builds only. 

I still don't have all this stuff checked in yet (yeah, I know, I need to get it done).  I also really need to write more documentation for WikiTalk...
