Ever since I idled in Orgrimmar I've had thousands of whispers asking for portals to X and Y. I don't mind doing it once in a while but when it becomes every couple of mins it becomes quite irritating.
This addon simply replies to the person sending the request with a simple message explaining that you don't give out portals due to all the requests you get so you don't need to.
Future versions will have some form of customisation in them to change message, set trigger lists, etc etc but right now its very basic just to reply to portal requests.
