Hi Matthew,

1) please note, I do not know Obj-C absolutly, but I will learn with you :-)

2) I again have CC this to Valentina list.
BTW, I have made Totte, and Eric Forget, but at least 2-3 more good experts
of Obj-C present here. One of them, Arthur Clemens, have made latest example
for Obj-C.

So guys, I offer you make small community and help each other resolve any PB
projects. Okay?

3) Matthew, what exactly line exists ?
