Investing in facebook on its first day?

[Dwight]

As many people know facebook is going public this friday. My portfolio has already grown a little, but this might be the only time a major corporation is going public for while. I was wondering if it is wise to invest in it on its first day. Moreover, what time of the day should I invest in it or what patterns to follow? I have the ability to set up a basic limited stock where I can set up a buy exactly when the market opens at whatever price I set. What is a good price or lower should I set if I invest right as it opens?
