Hiya! I'm petite_bb, also known as Alex [: I'm really looking forward to learning a lot from you guys about Blackberries, as I have a lot of questions about my Bold!
Before you even start asking questions, search the forums for the "blackberry 101" series. Its a great way to learn more about your blackberry, and a lot of the wonderful things it can do.
And if you do run into trouble, don't be afraid to come and ask for help. We were all new users once and most of us are pretty willing to help
