welcome to WebmasterWorld, compwiz02!
you're going to need something in the Pattern for the possible subdirectory.
otherwise http://www.example.com/support/general-forum/what-events-are-happening-today will redirect to http://www.example.com/forums/general-forum/what-events-are-happening-today.
the precise regular expression depends on whether or not you have urls requested such as http://www.example.com/support/general-forum/
there's also the possible uniqueness problem as you're essentially redirecting the contents of a directory and several subdirectories into one directory.
