In the General Questions section, and the other sections too, over to the right, in a blue bar, you will find different links. Click the one that says 'search'. Then type in some of the words of your question, and click 'enter'.

this method will usually get you answers faster than asking in a new thread, because most of the problems have already happened to members, and the answers are posted in some thread on this site.
