Adam, my question has nothing to do with etiquette. All I was asking about was if a spelling change in the subject line would effect (i.e. evoke) different results. It's probably not an issue. I just did some Google searches using the search formula +[pbs] [topic] site:///lists.ibiblio.org using the term masonoirum. Google immediately gives a prompt asking if I really mean masoniorum. This suggests that misspellings in the subject line can be corrected with impunity (at least with respect to the search results). Jim McKenney
