As a deaf citizen who uses text telephone (TTY) and a worker with deaf citizens with developmental disabilities, I urge FCC to require "chat feature" of video conferencing and all other video products for the following reasons: a) those who cannot read can include pictures obtained from clip art like software to send pictures across the phone lines after creating them on word processing files. b) it would reduce the cost of relay service if I can call a hearing person directly with a video product and communicate with him/her by typing text. Thank you. Sincerely, J. Roderick MacInnes
