I've been here for almost a year and I still barely post. I started my first thread last week. Some people can be really nasty, but some are really sweet and helpful, especially after you begin to sort of get to know them. If you feel like you have something to add to a conversation, post it. And don't let one or two people's rudeness turn you off, for every jerk on the board, there is someone who is quite nice and willing to share their experiences and knowledge with you.
Whatever happened to class?
