For a variety of reasons, I've decided to try and learn Ancient Greek. My college doesn't teach it, so I'm using this textbook instead: http://www.amazon.com/Greek-Intensiv.../dp/0823216632

I'm pretty excited about this (though it's probably going to be really hard), but I wanted to pick the Frontroom's hivemind for resources that could help me. I already know about the Perseus Project, but are there any other things I should look into if I'm going to learn this language? Or anything that I, as a native English speaker, should watch out for?
