The Information Desk forum is a safe and flame-free place for members (especially newer members) to post questions. It is also a good place for questions which do not easily fit in a single forum. However, if you know which forum on FlyerTalk is best suited for your question but don't want unfriendly responses, there are also a number of flame-free threads for program specific questions. They are often labelled "Newbie Lounge" but everybody is welcome to post questions there.
