I can't remember because I joined a really long time ago. If you do have to join it is the CMTC international president that runs it (his name is Lex). If you search CMTC on the Internet you should also be able to find images. Do you have any pictures of your son? I am pretty familiar with most of the pictures out there since I am in contact with several families. I could at least give you some idea if this is something to check into further.
