A list of 6max coaches is available here, in a sticky at the top of MHSH. A SSSH poster had mentioned that he didn't know such a list existed until he noticed it one day in MHSH, so I figured i'd put up a link.
Edit: Some posters have mentioned the above link doesn't work. Here's a direct link. Coaches: please contact Big_Jim (mod of MSNL) if you have info that needs updating.
