Please don't let all the references to the visually impaired discourage you from registering if you are not visually impaired. These sites are for anyone, not only the visually impaired to enjoy voice chat. They have been optumized for easy accessibility for the visually impaired, and there are many people already using them who have sight problems. But all are welcome, sighted or not. Or at least, they should be. You shouldn't have to be visually impaired or know someone who is, to join. I wish they'd update their policies to reflect this.
