Hello Miklu,
To search for something like " Stern of the Titanic", you need probably to be at the root of the English forum, because the search is done in the sub-forum part where you launch it.
You searched perhaps in the "Ship Simulator 2006 forum", so you needed to be at least in the 2008 part, as the stern of Titanic cannot be reached in ShipSim2006, I think.
Regards,
Luc
