I grabbed the latest svn of YAF [ a very nice forum I might add ] and converted it to 2.0.  After so more searching on the yaf forums, I found that he made another port of yaf [ with different options] and made some improvements.  Yaf is really easy to install and I installed it stand alone in about 5 minutes.  I also converted Keith Wells' forum module which is used to mount yaf into rainbow portal.   My next test is to install the 2.0 forum into a 2.0 rainbow.  Below are some screen shots:
