There are a lot of things that are not accessible. I am not a huge expert as I have just started messing with screen readers to help prepare myself for the future, but I would recommend downloading a screen reader or two and trying them out. NVDA is a good one according to almost everyone on this sub, but you could try some other ones too. Also testing out voice to text programs.

I haven't found many good how to videos or tutorials for this sort of thing either. I mean a how to set it up and navigate the program itself sort of tutorial. It would be helpful for people who are going blind as well as for parents of blind children who are trying to set things up for their children so they can have more access. Or for children setting up computers for their elderly parents or grand parents.

I would start off by playing around with some different accessibility programs and then come back to ask a more specific question when you hit a wall.. i.e. Is there a program to make flashplayer books accessible? As the Chinese say 加油！

I'm working on a b2b web app alone as my own startup, Ive been working on it for about 7 months and even have a github, its all in Java, I could always use a hand!

What about helping to make some open source software accessible? See below.
