Logging into ifwiki.org

I’m not sure if I have an account on ifwiki.org or not. Assuming that I don’t, I tried to register for a new one, but the signup page is missing the security check – it’s impossible for me to know just what to type in so I can go ahead. Does anyone here know what’s going on there?

Hm. Here it says: “What is the other magic word?”

I think the answer is “frotz” or “plugh”.
