Hm. I like to self-learn (I don't know the term.. teach myself? homeschool myself?) more than having someone tutor me.
I already have some of the best e-learning trackers. Bitme, Learnbits, and Bitspyder, but they don't specialize in e-books. It's a category on those sites but a lot of their materials are videos. I like reading much better than watching videos, so ebooksvortex is like a dream for me.
I can give 4 ratio proofs all greater than 1.5. Just ask for them. Anyways I'd really appreciate an invite or account to that site. Thanks.
