Treeman, I dare speak for the group (even though no one appointed me to do so): Just in case you haven't felt it yet, soon enough you'll see how we are pretty much a "happy family" together. You won't find anyone insulting another here. Disagreements are expressed civilly and the tone of voice that carries over is pleasant and cooperative. As you have already seen an example of joking, you'll understand how it is all said with a pleasant smile and the "victim" of a wisecrack takes it all in good stride and understanding that it's meant in good humor. I really hope you find your stay with us to be a pleasant and beneficial one.
Nice families tend to grow large.
