Lou, what I am asking did not change between posts. I can go to UserCP and see what I am subscribed to. But when I go to Advanced Search and try to search only the forums I am subscribed to, that is NOT what I get.
I did try searching each with "Also search in child forums" checked and unchecked, and either time it produced results that were in forums I am not subscribed to.
It certainly looks like advanced search should do this. In the top half I entered my Keyword and left User Name blank. In the lower half I left most items set to default including "Show Results as Threads" but selected "Search Subscribed Forums" and unselected "Also search in child forums".
