RE: Joining array elements
BTW, what George is showing there is an Array Slice. That's why the @
symbol is used instead of the $ symbol. I'd recommend looking it up in the
perldocs.

join ",", @array[2...$#array];
works nicely for me.

| Hello all

`-
Easiest way would be something along the lines of:
# Build a temporary array
my @tmp_array = @array;
# remove the first two elements
shift(@tmp_array);
shift(@tmp_array);
join(",", @tmp_array);
Hope this helps.
