Shouldn't "sporanino" be "sopranino"? There are only two or three occurrences of "sporanino" on the Web according to Google (one of them the one in question), but about a hundred of "sopranino". (My e-mail spell checker flags them both as wrong!) Also, could someone please interpret the ADO ratings for me? Is a black dot good or extremely bad? Is three starts "tops" or can it in theory go higher? --Alex
