I never had a chance to finish up the last two books. I got a little time and decided to plow through them. I've already finished Half-Blood, and I'm just about done with Deathly. My mind has been out of the Harry Potter universe for quite a while, so I have forgotten who some of the minor characters are and what some of the spells do.
Whenever I need a reminder, I just type it in over there on the site and instantly get refreshed. This site has been wonderful, thanks to everyone who created it.
