Questions asking about how appropriate CiviCRM is for a certain use case or environment, generally from the perspective of someone who hasn't installed CiviCRM yet.
In addition to technical and how-to questions, some users are looking at whether CiviCRM is right for them. This question is addressed in a general way in the CiviCRM user guide, but you may have specific questions about capabilities.
A question such as, "We are an environmental organization. Is CiviCRM a good fit?", will yield very little in the way of useful answers. Better questions describe how the data is currently stored, what interactions visitors might have with the site, or certain types of information that are tracked.
