There are two questions about this show that I need to have an answered.

1. Why doesn't the woman who played Piper have her name and image clips in the into of the show? She seems just as much a main character/actor as everyone else, so why shouldn't she be recognized?

2. The actress who plays Polly, is her name actually Susane Wong?

The answer for your first question, is that Piper was just to be a guest star on the show. For some reason she was in every show. I do not know if it is true but, that is what I heard. For your second answer if you look around the website, I bet that you could find it.
