Q: How do I find information on the site if I am not a Premium Member?
A: Contrary to the rumors, all information entered into the Allakhazam database can be found by all registered users; premium and non-premium members a like. Premium members, however, have access to a refined search. Unregistered users still have access to all of the information, but cannot post.
