Mike's a real busy man, he's juggling many things at the same time whilst still trying to keep his businesses, career, social life and the like afloat. This message forum's maintainance takes up alot of his time and trying to keep members in line and moderators in agreement whilst making tough decisions in keeping the messageboard a fun place for everyone, is alot of work for him especially with the amount of things that he has to attend to (personally i'm very surprised on how he does it).
Plus, Ruk recieves a shit loads of PM's and emails from different members (and ex members if they want to send death threats) so don't take it personal if he doesn't reply.
