I agree with all you two (Charlie and Locky) have said on this subject
And I personally think the all meet up and help each other is a very good way to learn (If not quickly it's a fun way to learn) and while every one stays nice it works
The problems start when one person feels that harm was caused through anothers fault I would have to have been literally attacked by a fellow bocker before I even concidered suing anyone and believe most of the bockers I know are the same
But when we start renting Gyms and doing major events (and teaching/coaching) the people organising such things ask "Who's in charge" and a lot of the time some poor mug of a bocker gets volunteered (and sometimes has little or no qualifications) said poor mug gets away with it most of the time but once in a while looses his/her shirt
We can't live life expecting the worse all the time but we all try not to be the one to get the bad end of things and like you said Charlie qualifications and experience helps a lot
I think that in todays climate Teachers/Coaches (especialy working with children or in areas where people can get hurt) are very brave and I take my hat off to people like Charlie and the like, it's not a job I would like to do daily, for me the risks are to high but thakfully some people are willing to do it and help the comunity a great deal
