Let me add that I'm not trying to be a post Nazi or squash conversation in any way. We WANT you to discuss ideas.
As in Derek's example, if you want a NO CHATTING thread, it's good manners to also provide another separate thread for discussion. He did so.
And like he did, it's good to make your request apparent. He has it in capital letters in his title and in boldfaced, large font in his original post.
I guess what I'm trying to say is.... read the thread. In Derek's thread, just skimming the title should suffice.
Edited to add: I just noticed that I'm only 30 posts away from ringing up all 3's. I'll probably retire at that point, and you can disregard everything above.
