Bad Signup Form at Raven-Seo-Tools.com site

Just read about this site at seologs. The signup form seems slightly weird with having only a single password field. Initially I didn't read the promo code field and just entered the password again thinking it must be asking for password as this seems to be a standard practice around to ask the user for password twice. But seeing that the password was being shown, I had a look at the left side and saw that it was asking for promo-code and not for password. Anyway I didn't had any promo-code for raven-seo-tools site so I just selected the free option and pressed enter. But it came back telling me that password cannot be more than 14 characters. I was wondering why they didn't mention it when entering the password field itself. So that is why raven-seo-tools.com site signup form is today's Bad Signup Form On the web. Here is the screenshot of the message on raven-seo-tools site.
