Hi, and welcome. You can put your story in your profile so it's always there for people to read and you don't have to type it over and over again. Or, you don't have to. Whatever you're comfortable with.
Start posting with a question, concern, whatever background you're comfortable giving.
Read the forum descriptions to figure out where you post best fits. There is also a sticky post at the top of General to help you with the abbreviations.
You'll find your way around.
