Hi Jem,
This is sad news which I am sorry to hear.
If you feel you have to leave us, then we all wish you well. But there is a way to continue using the web without sight - some of which I don't know if you have tried....
Woodelf, a long time contributor to these pages uses something called "Thunder Screen Reader"
You can download it directly here:
http://www.webbie.org.uk/thunder/ThunderStorm-Installer.exe
(The download should start straight away)
Thunder Screen Reader reads out the content of a webpage. Woodelf directs his Thunder browser to:
http://m.theanswerbank.co.uk/
Because it has less clutter for the screen reader to read.
This might be the place to start.
While we are not experts there are many of us who will do our best to help you get this kind of thing set up if you wish.
All the best,
Ed & Team.
