Welcome! You'll feel right at home around here, I think.
Radu is absolutely correct about Stone and Tirri: good books for what they are, but there are other well-researched and more comprehensive writings out there. For instance, Robert Elgood's work is outstanding, in my opinion.
By the way, Radu, I think Tirri (and any other author, for that matter) is perfectly fair game for criticism. I just have a problem when that criticism is leveled on
this forum in an impolite, uncivil fashion.
