Their landing page looks good, but their signup page is just horrible:
First of all, they're asking for too much information.
Second, you do not know which fields are optional and which are mandatory to be filled.
Third, users just don't know what to write in some fields like "ORU username".
Fourth, enter the 3 characters from the Security code just doesn't make any sense. Which 3 characters? ALL of them are characters. Numbers are also characters. Do they want us to write the numbers or the letters? Or only the characters of a specific color? Doesn't specify so it's very confusing.
I know from experience that if a user fails to fill a form the first time, they simply abandon it. That's why it's very important to ask specifically what you need in a form and not to ask too much information.
If they would simplify that form that would be an easy fix towards having more sign-ups.
Hell, I'd even signup as well but right now I'm unable to fill the form.
Also this header notice: "Only use a Gmail email address to register. Most other email clients will not work with our type of email server."
So now Bob can't join because he's got only a Yahoo email address? They should fix their e-mail server. It's not rocket science!
