Jump on in, the water's fine.
Let me echo a few others here. Nothing wrong with joining in even if you don't feel you have anything to add. We're all learning something, and the best way to learn is to ask questions. Just because nobody else has asked a certain question doesn't mean nobody else wants it answered. And I can assure you there have been plenty of times when someone asked me a question that I thought I knew the answer to, then learned something new in preparing the answer.
Questions are always welcome here. Even errors are welcomed here. The only thing we really get upset about is those who don't learn from errors or from the answers they get to their questions. And we even still let them hang around. I could name names, but that kinda wouldn't be in the general spirit of this thread, so for once I will take the high road.

It has always struck me as odd that fundies devote so much time and effort into trying to find a naturalistic explanation for their mythical flood, while looking for magical explanations for things that actually happened. -- Dr. Adequate
