Actually there were a few replies answering the question, but I felt this stream of the tread was heading in a stupid and neadlessly picky direction.
Hence my stupid sarcastic reply thinking it would bring discussion back towards Bee's question.
After all, the point to these forums is brain storming different ideas and although it was answered in the first reply, other ideas may provide an easier alternative. So reading useless replies like this one is just waisting time (Sorry Bee)

On rereading my above statement, I realise I may have offended others with the tone of which it has been written.
I opologise.
