Yes, SSI was a great suggestion, and moritz's recommendation was very helpful.
As to your question, a few years ago I was doing some volunteer work for a local community centre for the blind & visually impaired. It was more 'fun' than work, I helped with some things like cleaning up the place, preparing some meetings. I also lost a lot of games playing checkers (based on my experience, blind people are like shaolin kung-fu masters when it comes to checkers). It was a great time, the people were amazing, and if I hadn't changed my address, I would gladly lose some more games, eating cookies to ease the pain of defeat.
I did a simple website back then, some 5 pages with the contact info, and a "What's New" page. The centre has another website, it's updated regularly (it's part of some larger page for all similar centres). Unfortunately, it does not work well with software that reads the page contents aloud (navigation is too complex, the reader starts with some useless items that are located near the top of the page's source, and so on). So I made a simple page, with only the basic information, I made sure it's easily browseable with the monitor turned off, and it seems that it is useful, at least for some people. Since then, every month or two, I receive an email, and I add an item to the news page.
