Hi folks.
I was wondering something.
Last night, when I had someone visit my website wich you all may review at:
http://keithnet.dyndns.org
I was told seriously that the font is not optimal for people with low vision.
As I have committed myself to insureing my site is optimized for low vision users as well as screen reader users, hear is what I need to know.
It should be noted that I'm using Druapl Core without modification, I.e. No eextra themes, etc.
What I'm using is the default Draupl core layout as designed after an installation witht he bartic theme.
