Steve,
David's contributions to this group have been very valuable, both in terms of his experience in DIY and contributions to the FAQ's, and in following his change of life in turning his DIY hobby into his business, which many of us have followed. This latter aspect is something that we've watched probably around 5 people in the group do over the last 8 years, and it's something that very many more of us have considered doing, and may yet do in the future. This is why it's of particular interest to the group and directly relevant to DIY.
