I am in frequent discussions with the flexWiki guys and they have been most helpful.  They plan to add many new options as the time comes.  However, Today I figured out a bug which was occuring on XP SP2 across my 2.0 applications.  It had to do with security and privs [which is always my errors] and I was able to load ProntoWiki.  ProntoWiki was developed in VWD [ ASP.NET 2.0] and uses ASPNETDB membership by default.  I like that it has permissions and a decent user support.  It also uses master pages and we all know what that means :  AJAX!!
