Mike, don't worry about it. I've had several posts removed. Some through threads being deleted, but most down to the fact I was either hungover and grumpy, or acting like a dog on heat.
In fact I give it 30 minutes before my post in ABH on a bus goes.
As to how the rest of this site works, someone asks a question, the people who have no idea post a witty retort before being shot down in flames, then someone who actually knows gives them the correct answer.
