hey,
I looked at this, I was not pleasured with this, pretty lot of signs are wrong. therefore they are hearing who were learning a second langague ASL, you should ask for deaf people to get involed with this, deaf people know sign more than hearing people do. Therefore Hearing people cannot teach sign or make this program. You have to respect deaf culture.
for example if you are learning a second langauge spanish that you dont know about culture history, etc about your pride, but your first langauge is english, therefore you cannot teach spanish to the student who learning a second langauge spanish from you. When They learned spanish from you, they would meet mexicans or argentinians or briziallians etc they would not able to understand them.
please RESPECT their own first langauge they can teach them, you are learning the second any langauge therefore you cannot do that.
