Apparently, I Am A Robot...

Because when I try to comment sometimes on blogs, I cannot type the two words in the box correctly. I think the words are nescrift and yuosef, but I am almost always wrong. And then, I get sent back to the box (again), only to try (again) with another set of letters that I just won't get right. I have seen one site that uses common math. What is 3 + 4? the prompt will say. Well that is something I can read! And answer for that matter! It would be nice if people could have both options presented, and then we could all choose.
