Registration Test

Having trouble registering?

We have had problems with scripts, programs, and robots signing up onto the website. To prevent scripts from signing up, we have added a test to the signup page, which looks like this:


If you get an error that looks like this:

Spam detection -- It doesn't seem like you are a real person! If you disagree, read more here:

The error message you are seeing is generated because you did not fill out the test correctly, and the website thinks you are a robot. There are four pairs of sentences. One sentence in each pair is something a robot might say, the other sentence in each pair is something a human might say. In the screenshot above, we have selected the answers which represent what a human would say.

Please let us know at if you are still having problems, or if you have ideas about how to make this more clear for other users.
