Hello Stonehead, don't worry about not-perfect English, most English people don't even know what perfect English is.
But anyway, your English is better than my Helvetian.
Some people in England say "hoy" as well, though it's a bit impolite, as if shouting to a dog or a naughty child.
But I don't mind, as I
am a naughty child!
Enjoy your time here at LAF!
