Welcome to CB. I suggest clicking on the "NEWBIE" top at the top right. And reading the getting started guide and the 101 lecture series.
Remember the search function is your friend, try using it first to answer your questions, if you can't find an answer one of the CB members will help you out in no time.
Welcome again.
Welcome to Crackberry. Like GS said, check out the BB 101 series and also the FAQ forum for answers to a lot of your questions you didn't even know you had.
