it may csue clutter in the forum but what about ome kind of marker?? you know the thread title remains but it says *moved to GCC* or whatever and when you click on it redirects you to the moved thread - this could be left in place for 6hrs which should be enough if is an active thred - either that or look in your recent posts in your profile, if you click on it there it should take you to the movd thread
