Accessibility
As a personal project, I studied Accessibility and W3C guidelines in 2003.
After researching the issues online, I took a short course to grasp the coding restrictions. I then trained the 35 staff at my workplace on Accessibility. I also built a website for them to reference, which can be found here:
Since 2003 I have kept up to date with Accessibility and it is an integral part of my work. I now update my blog with all my latest findings.
