The Team Members of the Lego Guards are all more than happy to answer your questions, but they don't want to give out their e-mails. The best way to contact them is to send a message to their generic "info [at] legoguards [dot] net" and hope that a) no one thinks it's spam, and b) someone gets the message and gets back to you!
Actually, if you want to reach the coach, email alan [at] legoguards [dot] net and he will (almost certainly) get back to you very soon!
