There have been several questions about losing posts to the forums.  This however is not the case.  The forums have a filter that hides posts older than two months.  This filter is applied automatically, but it can be adjusted by users.  If you would like to see more (or even less) of the forum postings, look for the "More Options" button at the bottom of the screen. 

From there, you will see several different options of how you would like the forum postings sorted (by date or by thread author for example).  To see older posts, use the Date Filter and change it from its default of 2 months to a setting you would prefer.  You also have the option of saving these changes or just use them temporarily.
