Bad news, as they say, always comes in threes. First, I had to attend a family funeral on the other side of the world; then I fell ill, and finally, the motherboard on my dedicated server went into meltdown. As a result, all my websites have been offline since at least Wednesday of last week (14 January 2009), and I have been unable to answer a lot of questions in online forums, including my own blog.
The good news is that my server is now back online, and I hope to deal with the backlog of questions in the next few days. Apologies if you have been waiting for an answer.
