Welcome - you can search the forums using the search button. You can access the sub-forums by clicking on them. Important information threads are stickies which show up as the first threads in any one of the sub-forums. And you can ask your own questions in the appropriate sub-forums by clicking on the New Thread button.
There is so much information here and you will learn how to navigate the forum as you look around. I learned pretty much by trial and error with some help from other members.
This is a great community and I am glad you have joined us.
