And please, you ask lot of questions, pay attention to following notice:
I just want to encourage "anonymous" posters to register and start posting with a screen name. Answering anonymous posts is a bit like talking to someone who is wearing dark glasses -- except "Anonymous" might be any number of different people! When I reply to posts, it's much more satisfying to think that I am responding to an individual with a name. (It's just a suggestion. Go ahead and post anonymously if you really prefer it that way.)
