Amen! It occured to these people, they might think deaf people can not do presentations, but deaf people can prove it, deaf people can talk, but they can use sign language at the same time and interpreter is present to relay the presentation smoothly and that is definitely no problem. Once last year, I was doing some multimedia course, and I was asked to make a genre presentation and I chosen 'Drama' genre and the research was hard but I ended up presentating the audience with excellent power points and comments from myself, expressed the interest and I was so confident and they were impressed that a dead person could do the multimedia as even that I am deaf. ANYTHING can do to the deaf people, EXCEPT that they can not hear... remember, deaf people have eyes to be alert with communication and other things they occur to do!
Excatly! Only thing is they can not hear. But that is not a problem.
