It has become unorganized.  I go looking for stuff and its not where I 
think it should be.  Normally I keep things well organized but this has 
gotten away from me.  I'm sure I could go through and get it organized 
but I am starting to look at a clean install as a way to start fresh and 
do a better job this time.

I didn't see that, thanks.  As it turns out there was not much in them
