I currently have no way to tell what questions I've asked have accepted answers.
After the vote up and vote down graphics my screen reader announces "graphic check". I know clicking on this graphic will allow me to accept an answer since my reputation increases by two the first time I do it on a specific question.
If I go back to look at a question, there’s no way to tell if I’ve already accepted an answer though. Would it be possible to provide some non visual way of showing weather a question had an accepted answer such as alt tags on the “check” image that announce whether the image is to select an answer as accepted, or whether you're actually looking at the answer you’ve already accepted?
I may be way off base here since I can’t actually see how the screen is laid out but hopefully this makes sense to someone.
Update
When I look at this question with my screen reader the following is the element information my screen reader gives me when I ask for detail while on the "check" graphic. Based on this I setting either the alt attribute or title should work, although alt attribute would work by default while my screen reader would have to be told to use the title attribute instead of the alt attribute for stackoverflow.com and associated sites.
