http://pc-tech-upper-hutt.blogspot.com/ As time passes an increasing array of issues and articles have appeared on this blog. This is the second one today (15 November 2010).Much of the content consists of news articles, but it also contains hints, answers to your questions, topical material and other entries suited to the interests of members and visitors. It would be even better with the addition of your comments or the insightful things you have gleaned along your way. You are welcome to add material, comments and articles you have found of value. Indeed, it is important for you to do so. Without you, I might be talking to myself! That would not do at all.
