I share your sentiment toward the belts. We do not have uniforms and no one wears belts during training, so it really doesnt matter. The instructors know everyone by name and how long they have been there except for the people in their first couple of weeks. At our school, you start at beginner class but everything beyond that is by invite only. Essentially the instructor makes a case by case judgement on what you can handle and thats how you move up into more advanced training. There are classes on MT, boxing, jiu jitsu...if you go through "level 1" classes enough times and the instructor thinks you can defend yourself well enough not to get hurt in a higher level, they will invite you...all that said, I am in for self defense period, i really couldnt care less about rank as long as it doesnt bar me from participation in advanced training. I could see, that if i change schools it could be hars for me to prove on paper my capabilities.
