Where did all the old posts go? - They're here. Here's how to find them
Many people are looking at the sub-forums and thinking that all the older content has been removed. It hasn't, it's just been filtered so that under the default settings, only posts newer than two months old are displayed.
All the old posts are there, it's just a matter of setting your options to viiew them.
At the top right of each subforum menu, there is a selection for Sorting and Filtering
When you click this, you will get an options page:
This is the default setting. Only the threads with posts less than two months old will be displayed. To change this, press the "drop down" button on the "with date" option and select "show all" as shown below.
Set the "With Date" selection to "Show all", Save the changes and you will see all the posts in that subforum.
You will need to change this setting manually for every sub-forum.
