I agree that registration should be made not necessarily harder but more thorough. So that it's not just a quick one minute job.
There are two things I don't get - one, why Benet doesn't seem to read the rules and two, usually if a page is protected and you can't answer the questions then it probably means you're simply not ready for the material within - so why bother asking?
For example, I am very sure that the Eugene question is from Derren's website, and his material is definitely not stuff someone who's only been involved in magic for a short period of time should attempt.
Really most of those questions are things that anyone who has even looked around these forums properly should know the answer to.
