(I got an email from this gentlemen and wanted to let you all know about his service. I haven't used it yet myself as I have my own FTP computer... However, it sure seems like a great idea! his email is copied below...)
My name is Bernard Maldonado. I read your blind resources site and found your link page. I'm writing you to let you know about a blind friendly service I operate It's called Blind FileSharing and the site address is http://www.blindfilesharing.com/ It's a site that does not use graphics or capchas and allows visually impaired people to share files in an easy to use environment. I don't advertise, so it's not a free service. However, I think it's quite inexpensive. Basically, it only costs 2 cents per file transfer. The size of the file does not matter.
