I hate to whine in only my second post on this site, but here goes:
1. The black background with white/gray letters can be hard for me to read. I normally use the Firefox browser, so I switched colors on that, but the verification text to allow posting doesn't display. I tried the "Listen to the letters" option, entered the letters as spoken, and got an error message. Is the form not compatible with Firefox?
2. In Internet Explorer, with the black/white color scheme, I still have a very difficult time figuring out the verification text and have to use the "Listen" option. I haven't tried changing colors in the IE browser.
