Your scholarly interest is very welcome here, and would add alot to discussions. As we're saying, just ignore the flamers. The many good folks here know what's what - a flamer can't bring you down in our eyes, so as unpleasant as it is to read, just concentrate on the good stuff that vastly outweighs the inevitable Net bad apples. Nothing new said, just want to throw in my vote of confidence.-chanteyranger
