Leafwind places those as activity checks. Although he might not know all the details of a persons absence, there is usually a large amount of time given in which one can respond to them. If you cannot sign on even for a moment in an extended period of time, you must send me a forum message detailing why that may be. Otherwise a person will easily be forgotten in the vast amount of dealings the wardens have in their schedule, but if a message is sent with a proper excuse, then I will make sure that the person is not kicked out for inactivity.
