Welcome!
It's simple. First, use the board's search feature to see if you question has already be asked/answered by someone else. Second, if not, then find the appropriate area of the board and post your new question. Try to use a descriptive title in your post. Don't put something like "HELP ME!" or "Newbie Dummy Needs Help". Those titles aren't too intuitive. Try something like "Xorg.conf Problems w/ Fedora Core" or "Ubuntu GRUB Failure".
Have FUN!
