Mate I know exactly what you mean. I felt the same way a few weeks ago when my wife passed away. It seemed to me at the time that other people had stopped using the thread and I felt incredibly guilty.
I spend most of my time in the MessyMascot update thread these days. If you're ever feeling a bit down or lonely, just pop in there. They are a great bunch, basically the same people who frequent this thread, so no introductions needed. They'll all know your situation. They are just there for you and of course by being in there you're also showing your support for Messy and what he's going through at the moment.
