Look at this thread on this forum:

This link should be to the last page or so. At any rate, pretty much anywhere on this thread you will see posts that have text that is blacked out.........If you click and highlight the black area, you are able to read the text. This ability is what I am wanting to add to my forums, but I can't figure out how.
