A lot of stimulating information in one spot, its been 15 minutes so far and I am still on here in a different window. Again though the information being presented seems a bit overwhelming, it being since I dont really have a previous experience in it. My buddy is next to me and hes pretty knowledge in this topic so hes making this clearer. I read some other comments users left, some where negatively reflecting this site. My suggestion to get some one to assist you because its really interesting material. By the name you already know its focusing on the topic of curves, more over on what curves are, their importances and typical uses.
