On YA why can't I answer any questions I can type them in the box but cannot submit?

There is a new glitch - Internet Explorer is identifying one of the latest changes on Y!A as a security risk. You may see a box at the bottom of your page warning you that "Only secure content is shown." To post answers you need to click the "Show all content" button - because part of the insecure content they are blocking is the submit button!

Alternatively, switch to a different browser - I have found that there is no problem using Google Chrome.

Another answer is the asker blocked you.
