Gosh really sorry didn't mean to upset anyone. I was just desperate as I really didn't want to use them things anyway but needed a way to do it quite quickly. I wasn't sure of their ethical status as they do seem to have some 'good' feedback on the net, safe in rivers and all that jargon.....so it says. I'm just stupid I guess. Once again so sorry.
I love this website community and don't want to be a badie.
