We have a spiffy "Welcome Area" here on reenactor.Net. It will show you how to get around and do some of the things we've found need a little explaining... to visit our Welcome Area, go here: http://www.reenactor.net/new_area/welcome_message.html
A system of rules and points that allows a reenactment to be more realistic through goals and objectives. Yes, it sounds complicated, but in practice, it is NOT! Give it a try!
