This is by far the most engrossing forum I have ever read. To those those who are willing to share their knowlege with strangers such as myself, thankyou. I learnt more from members of this forum in a matter of hours than i could ever have learnt from years of weeding through scraps of information. As someone who has worked like a donkey on construction-sites for a living, it puts a smile on my face to know that there are plenty of people playing the system for reward with wit, skill ...oh , and a lot of hard work too, I'm sure! So congratulations on a tight community. I look forward to contributing something of value in the future.
