Welcome aboard Anna! A good place to get acquainted with these discussion forums and the site in general is to go to the "Need Help - Start Here" tab of the discussion forums. There's a TON of info there and reading through that will give you a good starting point. And if you have any questions, please use the "Search Discussions" box (can usually be found at the top right corner when you are perusing the forums) and see if threads have already been opened about the same or similar topic. If you can't find any answers to your questions feel free to ask and there's always a kind soul that will stop by to give his/her insight.
Cheers and welcome!
