How do I make vBulletin accessible for blind users?
 

I'm running a vBulletin-based forum that will be accessed by many people using screen readers and I need to make the site as accessible as possible.

Are there any plug-ins to help with this?

I'm not very technically-minded with regards to manual changes to vBulletin's inner-workings, but I can follow step-by-step directions.

Right now, my superiors are most concerned with alt text on all the indicators, such as those for new posts.

Any help that anyone can provide is greatly appreciated.

Thanks.
