I did a little investigation, and found out there is indeed some issues with the "Latest Forum Posts" widget in the right hand navigation.  The author is trying to figure it out, but has not been able to find out what is wrong.  It appears as though it is somehow related to long posts, as short ones appear just fine.  The issue is that if you are not logged in, you may not see all the latest postings, even though you can view them if you are not logged in.  If you login, you will see all the latest postings.  Not a big deal, but just wanted people to know it was a known issue and is being looked at.
