Welcome to the Fakku community. If you suffer from shyness, I would suggest you be wary of posting anything in the Incoherent Babbling section, as people's remarks can get rather spiteful, especially if you're new. Posting there will help you thicken your skin to the sarcasm of others, however, so I suggest you monitor all the threads so you learn how everything works here.
Most of all, enjoy yourself and remember that you are as anonymous as you want to be, so feel free to express yourself because we really don't know who are unless you tell us. We all have common interests here, so no one is really an outsider, unless they choose to be.
I hope you quickly find friends who will make your time here enjoyable.
