Hi, let me answer your question about posting first:
one the top of every post page on the left side under the Hello (your name) - there is a HOME button (it is orange)
Click on it, to go to the entire support board.
Next - select a section that seems to fit your question - or use Support - General Support (child board).
Click on that and you will get a Topics pages. Look for the NEW TOPIC button, click on it, and you will have the ability to pose a new question.
Hope this helps.
