No problem. If you haven't already done so, go to thread under General tab marked "Getting Started - A guide for new throwers." The games consist of 5 to 9 events that you compete as an individual against athletes within your group. Groups can be based on age, athletic skill set, gender and weight. Masters = age 40+, Amateur B = age <40 and of beginning or moderate skill set. Not every group competes at every festival/games.
There are no clubs rather organizations that run the Heavy Events part of the festivals. There are various throwers that will get together for practices, travel to different festivals and sometimes just hang out. I'll let Bryan know that you're looking for people in your area to practice with and pick up pointers. You may want to register on
http://www.nasgaweb.com which is another board that is the North American board which also has a section for newbies.
Let me know what ever questions you have.
