Your text says "New Forum:" and then right under that it says "Forum 2005-2010 (read-only)" which would appear to completely negate your theory.If you check the REAL new forum home page you will see a tiny fraction of those message counts.
The index to the old forum is shown in the new forum for your convenience. The old forum is still the old forum.The new forum has 10,030 posts as this is written (and increases every minute) while the old forum has 354,804 posts (and is locked)
You are correct. I don't understand what you are asking.First, you seemed to be asking for the search function to search only the new forum (the 10,000 posts).
