Thanks again, I'm flattered... :-) I really love doing tutorials and sharing the little knowledge that I have. It's nice to know that  I seem to be able to convey something useful. As to my voice: I've seen a lot of video tutorials, both commercial and free, and I liked most of the voices, but let me tell you, it's definitely weird to hear one's own voice. :-) I still have to get used to that...
